1. Introduction

Through the ages, humans have invested considerable efforts and resources to construct and maintain a favorable environment for growing and breeding crops and ornamental species so as to foster a diverse spectrum of provisions and services delivered by plants [1][2][3]. As a result, one of the closest spaces of plant–human interaction–the home garden–is seen as a multifunctional and multilayered land-use system that provides not only for production of food and fodder, ornamentals, medicines, fuel, etc., but also for human cultural and spiritual well-being [4][5]. Depending on the climate, geographical region, cultural and economic background of their keepers, home gardens differ in their structure, natural diversity and purpose [1][6][7]. Private gardens in the tropical zones have been more frequently discussed in their current relation to self-provisioning, presenting an important part of the livelihoods of economically struggling communities [8][9][10][11][12]. A broad variety of plants used as food are reported in a number of studies dedicated to the past and present of the cultivation of edible species in European home gardens [13][14][15][16][17]. However, being largely supplanted by the globalized agri-food industry, temperate and especially European home gardens and their owners have drawn less attention [5][16]. Since the beginning of the new Millennium, European home gardens have presented a colorful spectrum in East–West direction. In Western and Central Europe, they have been mostly appreciated for their cultural value, harboring mainly ornamentals and fruit trees, while to the east they have ensured staple food and/or fruits and vegetables for their owners and in some cases also for the market [7][18][19]. Important topics for researchers of European home gardens have also been the loss of agricultural diversity, preservation of biocultural heritage and the role of gardening in the distribution of invasive plant species [5][17][20][21][22][23]. However, with the bloom of urban gardening, activated by sustainability objectives and more recently by the food import shortages imposed by the Covid-19 pandemic, there is a growing body of evidence showing that (home) gardening in the industrialized societies (namely in Continental Europe, Britain and North America) is a vital activity that could not only alleviate family/local food insecurity but also contribute to the mental health and subjective wellbeing of those involved in it [8][24][25][26][27][28][29][30][31].
In Eastern and Central European countries, and especially in their rural regions, where substantial socio-economic and agricultural landscape transformations have been evident since the abolishment of Communism, the fate and development of home and allotment gardens as a food source were considerably different compared to their western counterparts [32][33]. Through the years, different studies have related subsistence farming in Eastern Europe with the overcoming of economic challenges to the poor communities in these countries [34]. However, recent data have shown that the meanings that underpin self-provisioning by growers of allotment gardens from Central and West Europe were quite similar [35][36]. Nevertheless, it has also been shown that for East Europeans, food growing is not only a simple means of food supply but also a complex culture-related activity that needs additional research [37].
Subsistence farming was a primary livelihood in Bulgaria until the collectivization of farm land after the end of World War II [38]. As a result, home gardens, and later, allotments granted to the urban population, remained the main places where Bulgarians could freely operate as farmers during Communism. The popularity of subsistence farming in countries of the former Eastern Bloc at the beginning of the 1990s was negatively correlated with the percentage of the population employed in the agriculture sector, with Bulgarians placing food growing for personal use among the main activities that supported their overall living standard [39]. A recent study has shown that in several peri-urban villages around Sofia (the capital of Bulgaria), vegetable gardens and greenhouses were found in 31–71% of the examined yards, while flower beds and lawns were less frequent (15–53%), depending on the terrain, planning and individual preference of the owners [40].

2. Characterization of Home Gardens and Their Owners

The characteristics of the studied home gardens and their owners are shown in Table 1. Home gardens sized over 100 square meters prevailed in both lowland (≤300 m above sea level, coded hereafter with LL) and semi-mountainous and mountainous settlements (>300 m a.s.l., coded hereafter with SMM), at 93.8% and 57.6%, respectively. The number of smaller gardens was higher in SMM settlements, where yards of less than 100 square meters were frequently found due to the elevated terrain (p-value < 0.01).

1 Home gardens are grouped according to the settlement elevation: LL, lowland settlements ≤300 m a.s.l.; SMM, semi-mountainous or mountainous settlements over 300 m a.s.l. 2 Fisher’s exact tests were used to compare the characteristics of home gardens of LL and SMM groups. 3 Kruskal–Wallis (K-W) test was applied to assess owners’ characteristics (sex, age and persons involved in gardening per home garden) in relation to garden size and FGA. 4 Sample sizes vary due to missing data in the different variables. NS: not significant (p-value > 0.05). N: Sample size; sq. m: square meters.
Traditionally home gardens were entirely fenced, arranged in the front and back yard, proportioned according to the position of the house and the size of the street-facing part of the yard. In the mountainous areas (e.g., Rhodope Mountains) small vegetable plots were also located outside home yards, occupying every flat space with fertile soil in the villages; these were fenced only against animals. Traditionally, orchard trees, small fruit and nut shrubs, as well as (semi)-cultivated greens such as stinging nettle (Urtica dioica L.), sorrel (Rumex acetosa L.) or garden orache (Atriplex hortensis L.) occupied the periphery of the gardens. In home gardens with a larger number of fruit trees, these were distributed unevenly and rarely in rows to allow cultivation of the garden’s maximum surface area. In 82.7% of the home gardens Vitis vinifera L. vines were trained on pergolas so to shade over the home/yard entrance, while in 13.4% of the gardens, wine grape varieties were found on trellises, in rows, similarly to local vineyards. The latter was of a specific interest to the participants producing wines and spirits for their own consumption. Only in about 10% of the gardens did we find both types of vine cultivation.
Ornamental plants typically bordered food growing plots and yard pathways, or were set in narrow strips or patches close to the house and along the fences to free the major portions of the home garden for cultivation of mainly annual edible plants, medicinal plants and spices, and occasionally fodder for animals. The food growing area (FGA) in 63.1% of the studied households comprised more than 2/3 of the total size of the garden and in most of the remaining gardens ranged between 1/3–1/2 of their total size (35.4%). The size of the home garden and FGA correlated positively in SMM settlements (Spearman ρ = 0.706; p-value < 0.01) but not in the LL ones (Spearman ρ = 0.273; p-value = 0.207). However, there was no statistically significant difference between LL and SMM groups in the FGA proportions. The larger size of the yards in LL settlements allowed garden owners not only to develop substantial FGA but also to create lawns and/or other recreational spaces such as garden arbors.
The food growing area was typically unified or separated in plots by temporary pathways. Raised beds were not found as a garden practice. Crop rotation was applied to maintain soil fertility. Cultivation plots were designed according to the irrigation arrangements on site. Irrigation of the open plots (furrow method) relied on private wells, adjacent water bodies/springs and/or tap water. To manage water shortages and high water bills, drip irrigation was maintained, yet rain-water collection systems were scarce in the visited households.
Food plant growing in facilities that provided greenhouse conditions was recorded in about half of all home gardens. The frequency of these facilities slightly prevailed in SMM (56.2%) compared to LL settlements (42.4%, p-value = 0.325). Cold-frames and low-tunnels were used for seed germination and growing of seedlings in late winter and early spring. However, to protect against acid rain, hail and frost, some owners preferred to cultivate tomatoes and cucumbers using plastic foil greenhouses for the whole growing season both in SMM and LL; some households had the option to cover more than 20 square meters. Regardless of the installed facilities for protected agriculture, winter was typically a resting period for gardening activities in the visited gardens. Vegetable growing in greenhouses outside the season (i.e., spring onions and lettuce in October–November) was reported by participants from southern parts of the country.
Gardens were owned by families (41.5%) or single-person households, among whom females prevailed (38.5%) compared to males (13.8%). Most of the owners were seniors (late adults) with an average age of 68.52 years, and a majority of whom were within the age range of 56–75 years (55.8%). Those in SMM settlements were slightly older. The percentage of people under 55 years of age among our participants was low (13.5%). The age and sex of the participants were not significantly associated with the size of the cultivated FGA or the size of the garden as a whole. Similarly, regardless of the variations in garden and FGA size, most of the home gardens were maintained by one (27.7%) or two (49.2%) persons. The participants shared that mechanized ploughing was used when it was possible, and all of them used agrochemicals (pesticides and fertilizers). In this sense, the home gardens were more or less arable land that provided all plant produce for the household except for wheat grain. Our participants also often referred to as “gardens” any (mainly irrigated) plots outside the settlements that they used to cultivate through the years to supply additional food. However, no one regarded themselves as a “gardener”, as this term remains reserved for occupational gardeners. Almost all participants shared that they had some involvement in industrial agriculture currently or in the past, due to the obligatory participation of students and workers in agricultural activities required by the state before 1989; however, only two participants had specialized training in agriculture or horticulture.

3. Plant Diversity and Crop Preference

We documented in Bulgarian rural home gardens 145 cultivated and semi-cultivated plant taxa used as food, medicinal and aromatic plants, and as animal fodder. A list of all recorded taxa is presented in Supplementary Table S1 (https://www.mdpi.com/2223-7747/10/11/2520#supplementary). They belonged to 40 plant families and 98 genera, with members of the Rosaceae family being the most numerous (22 species, 15.2%). The following plant families were less represented: Lamiaceae with 14 taxa (9.7%), Fabaceae (12 taxa, 8,3%), Amaryllidaceae (11 taxa, 7.7%) and Asteraceae (10, 6.9%). Prunus and Allium were the richest in taxonomic genera cultivated in the home gardens (9 taxa each), followed by CucurbitaRibesBeta, and Brassica with 4 taxa each.
Fruits were the most frequently used plant parts (35.9%), followed by leaves (24.1%). Whole herbage (17.6%), mainly of culinary herbs, leafy vegetables and/or medicinal plants, was used for salads, herbal teas and/or as pastry fillings. For the preparation of pastries, ruderal species such as Papaver rhoeas L., Capsella bursa-pastoris (L.) Medik., Stellaria media (L.) Vill., and Ranunculus arvensis L. were carefully preserved while juvenile in the garden wherever they appeared, whereas other semi-cultivated species such as Portulaca oleracea L., Rumex patientia L., Urtica dioica L., and Phytolacca americana L. were kept where they did not interfere much, e.g., along the fences, among the vegetables, or in the flower bed. Seeds of 14.1% of the taxa were used as staple foods (legumes), snacks (legumes, cucurbits, sunflower, hazelnuts and peanuts), or as spices (the representatives of Apiaceae—dill, fennel, parsley, lovage, and coriander).
There was no significant difference in the average total number of taxa cultivated in the home gardens for food, medicinal purposes or fodder when LL and SMM settlements were compared (Table 2, Fisher’s exact tests p-values > 0.05). Home gardens in LL settlements tended to comprise a higher number of crop taxa. However, the garden richest in taxa (53) was in an SMM region, had been recently enlarged by merging with a neighboring yard, and was also close to the Bulgarian-Greek border, hence under Mediterranean climate influence. In all gardens, at least 10 cultivated taxa were edible, but in most cases this number was over 20. Plants used as culinary herbs were often used also as medicines. Nineteen plant species grown for medicinal purposes were employed as herbal teas: e.g., Agastache foeniculum (Pursh) Kuntze, Sideritis scardica Gris., Melissa officinalis L., Ocimum basilicum L., Tilia tomentosa Moench and another six for extracts (e.g., Valeriana officinalis L., Lilium candidum L., Juglans regia L., Allium ursinum L.). They were applied as remedies for cough, stomach and intestinal discomfort, relief of mild nervous tension, skin conditions, etc.

NS: not significant (p-value over 0.05). SD: standard deviation.
A small number of the cultivated taxa (19) occurred in all the provinces, and only six were found in every visited garden (Table 3). The fruiting and bulbous (mainly onion and garlic) vegetables and culinary herbs were the groups that were obligatory for all home gardens. The first two groups occupied the greater part of the gardens as well as most of the greenhouses. While winter white and yellow onion varieties (A. cepa L. Cepa Group) and garlic (A. sativum L.) were regarded as “ordinary”, red onion varieties (A. cepa L. Cepa Group) were of explicit interest in several regions where local landraces of this crop were grown under the name of the specific village, e.g., ‘Peshternski luk’ (Peshterna village, Lovech Province), ‘Reseleshki luk’ (Reselets village, Pleven Province) and ‘Banichanski kromid’ (Banichan village, Blagoevgrad Province). The specific and appreciated quality and taste of these landraces were attributed to the local water sources. Red onion varieties were used for preparation of traditional foods typical for the village or the region and were celebrated on occasions with specially organized local festivities related to their harvest.

The remaining Allium species (Allium tuberosum Rottler ex Spreng., A. schoenoprasum L. and A. vineale L.) were far less typical for the home gardens, with the latter two used only in salads. Consumption of fresh salads in the winter–early spring period was also a main driver for cultivation of lettuce (Lactuca sativa var. longifolia (Lam.) Alef. and Lactuca sativa var. crispa (L.) Schübl. & Martens) and radishes (Raphanus raphanistrum subsp. sativus (L.) Domin). Brassica varieties were used fresh and also as major ingredients for pickles.
Fruiting vegetables, and specifically those used in popular salads and vegetable dishes, were of primary interest to our participants. Most of their investments in greenhouse construction, irrigation systems and seedling maintenance were dedicated to the cultivation of crops from Solanaceae and Cucurbitaceae. In the LL settlements, fruiting vegetables frequently occupied 1/5–1/3 of the FGA, comparatively more than in SMM gardens, or 81.3% and 57.6% of the gardens, respectively (Figure 1a,b; Supplementary Table S2; Fisher’s exact tests p-values < 0.05).
Figure 1. Preference given to crop groups as parts of the food growing area (FGA) across studied home gardens in: (a) lowland settlements (LL), n = 31; (b) semi-mountainous and mountainous settlements (SMM), n = 33. * Fisher’s exact tests p-values ≤ 0.05.
Cultivars of Capsicum annuum L. were found to be most diversely consumed—raw or roasted in salads, in cooked dishes, or as a snack; stored frozen or in preserves such as the traditional relish lyutenitsa (together with tomatoes, aubergines, carrots, etc.) or in pickles; as well as for preparation of sweet paprika and chili powder.
There was no significant difference between LL and SMM settlements in preference for cultivation of the remaining food plant groups. Herbs and spices (29 taxa), arranged near ornamental patches or in between vegetable plots, mostly occupied less than 1/5 of the FGA both in LL and SMM settlements (Fisher’s exact tests p-values > 0.05). Similarly, 60–90% of all participants cultivated legumes, tuber and root vegetables, leaf and stem vegetables, and berries and small fruits on less than 1/5 of the FGA (Fisher’s exact tests p-values > 0.05). Still, home gardens with poor soils and irrigation opportunities (SMM settlements) were more likely to harbor slightly larger plots with legumes, tuber and root vegetables.
Cultivated plots had very dynamic use, and their owners had detailed plans for the first and second croppings throughout the FGA. Leafy greens, together with spring onions, usually occupied the greenhouses and sheltered plots before the start of the active growing season (February–April). Consequently, they were then replaced by fruiting vegetables, potatoes or legumes. To maintain maximum utilization of the FGA, all unsuccessful plants were immediately substituted with seeds or seedlings bought from the nearest farmers’ market or obtained from friends and relatives. This was mentioned as specifically important for garden owners using tap water for irrigation.
Legumes were represented by eight species. Apart from the common bean, Phaseolus vulgaris L., which was most popular in the home gardens, five pre-Columbian staples, i.e., fava beans (Vicia faba L.), grass pea (Lathyrus sativus L.), chickpea (Cicer arietinum L.), lentil (Lens culinaris Medik.) and cowpea (Vigna unguiculata (L.) Walp.), were scarcely grown in gardens in southeastern parts of the country. Those were maintained only for the preparation of a few traditional foods, hence their limited use had reduced them to garden crops. Conversely, interest in pole bean varieties and landraces (Ph. vulgarisPhaseolus coccineus L. and in some areas, Phaseolus lunatus L.) was higher as they occupied less space and allowed intercropping with corn and Cucurbits. Recently, these varieties have attracted higher consumer interest due to their large seeds, which are preferred in various salads.
Corn (Zea mays L.) was the only species representing Poaceae in the home gardens. In more than half of LL settlements, corn was missing, and in the rest, it occupied less than 1/5 of the FGA. Corn was more frequently sown in SMM settlements where local landraces, specifically used for preparation of cornbread and typical dishes, were found in very limited areas for preparation of festive foods for community occasions and for preparation of specialties in local restaurants. Our participants from the Rhodope Mountains shared that reduced growing of corn, along with other grains such as rye (Secale cereale L.), was related to the improved access to wheat flours and corn produced in other regions.
Fodder plants were the least represented group in the home gardens. They were preferred by owners breeding farm animals within their home premises to ensure easy access and to reduce transportation of the fodder. Medicago sativa L. was the only one sown specifically as fodder. Corn, fodder beet and herbage of various legumes were also used for the same purpose.
Apples (Malus domestica Borkh.) and sweet cherries (Prunus avium (L.) L.) were found to be the most favored fruit trees across the country. They were followed by pears (Pyrus communis L.) and Prunus taxa. Pomoideae and Prunoideae were typically found to range from 3 to 10 individuals per garden, and only keen grafting enthusiasts maintained more varieties and individuals in their home gardens (Table 4). Several species introduced from the Mediterranean region and subtropical Asia were found to be popular all over the country, i.e., fig (Ficus carica L., 27 gardens), kiwifruit (Actinidia deliciosa (A.Chev.) C.F.Liang & A.R.Ferguson, 11) and lemon trees (Citrus limon (L.) Osbeck, 17). The latter were predominantly sheltered for the winter period. In the southern parts of the country, with Mediterranean climatic influence, there was a greater variety of such species: Ziziphus jujuba Mill. (15), Laurus nobilis L. (9), Eriobotrya japonica (Thunb.) Lindl., (7), Prunus dulcis (Mill.) D.A.Webb (7), Punica granatum L. (6), Diospyros kaki L.f. (5), and Morus nigra L. (1). Juglans regiaCastanea sativa Mill. and Corylus species were found less frequently due to their incompatibility with the vegetable plots.

4. Seed Saving and Plant Food Self-Provisioning

Food provisioning requires access to seeds and other planting materials, as well as relevant skills in horticulture. Thus, the abilities to collect quality seeds, to produce healthy seedlings and to obtain larger yields were considered central for the creation of a “successful” rural life. Home-grown crops and homemade foods were claimed to be more valuable and of higher quality compared to purchased ones. Seed saving of crop varieties was practiced by 60% of the participants, but they had various attitudes regarding seed acquisition and conservation. In terms of origin, three sources of seeds were recorded–marketed seeds produced in Bulgaria, imported seeds and heirloom seeds/local landraces obtained outside the market. Interestingly seed saving was not significantly related to food self-provisioning, and those who were interested in seed saving were targeting all kinds of seeds regardless of their origin (p-value < 0.05, Table 5).

As the main focus was placed on sufficient and quality harvests, the origin of the crop varieties was not imperative. Seeds obtained from the national market were claimed as least favored for ensuring quality seeds for saving (p-value < 0.05). Very often, garden owners were disappointed by the quality of the seeds obtained from Bulgarian markets (low or uneven germination, variety or even species mislabeling). Seeds found available on the Bulgarian markets were mainly of hybrid (F1) origin, due to which seed saving was deemed unsuccessful in most cases. If the saved seeds gave satisfactory harvests in the second year, they were kept, reproduced and gradually perceived as “owned” seeds. Very often, garden owners who were respected for their skills by their communities had specific interest in saving seeds from local landraces, which they also spread among their fellow villagers.
Nowadays, there is growing consumer interest in “traditional” tastes; hence, the cultivation of heirloom seeds has become popular among garden owners. However, only two of our participants kept records of the origin of their crops, focusing rather on the skills needed to grow food plants than on the preservation of local landraces and/or heirloom varieties. The cultural and ecological values of local landraces were not entirely understood, especially by seniors that regarded local plant diversity as granted. Some garden owners had higher trust in imported seeds, especially when the taste of the obtained produce was close to their expectation.
Adding variety to the cultivated crops in the home garden was rarely considered as posing a risk of introducing invasive species or eroding local plant genetic resources. The participants had no opinion or were hardly interested in plant conservation as a grassroots activity/responsibility. In some cases, local cultural centers took the initiative to investigate and collect the knowledge about local landraces and occasionally created small seed banks representative for the village. A push forward for such activities was the collaboration of the cultural centers with Slow Food, an international organization maintaining a worldwide online catalogue (Ark of Taste) of threatened foods, among which a considerable share was occupied by fruit and vegetable varieties and preserves from them. The pink tomato from Kurtovo Konare, Kurtovka apple, Smilyan beans and others are part of the Ark.
During the interviews, seed saving was described as mainly female activity, performed by elderly women, grandmothers and/or mothers-in-law. The informal exchange of seeds was favored especially when the provider or his/her ancestors were known as skillful garden keepers.
Seeds from crops of Solanaceae and Cucurbitaceae were collected from specifically selected fruits, while those from legumes and corn were collected from healthy, strong plants to avoid transmission of diseases for the next year. Seeds were stored in various repurposed containers, envelopes and jars. Home “seed banks” were kept in storage rooms in cool and dark places. Mentha spicata L., Origanum vulgare subsp. hirtum (Link) Ietsw. and Juglans regia leaves and salt were used as traditional insect repellents.
Most of the studied households (86%) relied entirely on their home gardens for the provision of plant produce (except wheat grain) for the whole year (Table 6). Most participants from the lowlands (93.3%), who also managed bigger gardens, produced enough to be independent from the market, while some of those from SMM areas (22%) still relied on the market due to the smaller garden size. Larger home gardens and FGAs, logically, allowed their owners to process higher quantities of their produce into fruit and vegetable preserves for the winter or to offer the surplus for exchange, tastings at local events, or on the local farmers’ market (Chi-S p-values = 0.029 and 0.036, respectively).

Few participants who used their properties only as summer villas opted only for fresh produce for the summer (13.8%). Our participants invested substantial time and effort into processing the produce from their gardens by drying, canning and pickling in order to store it for the winter. Preparation of canned food included not only preserved vegetables and fruits but also ready meals and starters that were not found on the market or were not of the desired quality and/or local taste. Preserved plant foods were consumed seasonally, in winter–early spring, and consequently replaced by the fresh early leafy vegetables (lettuce, spinach, radishes, etc.). Especially older participants, living alone, preferred to utilize most of their harvest by processing, thus providing food not only for themselves but also for their children, other relatives and friends.
Food self-provisioning from the garden was perceived by the participants as an almost inevitable activity in a rural community. However, it ensured not only self-sufficiency but also catered to their personal pride and recognition within their community. Quality non-perishable foods were shared within the extended family and the whole community and also served as customary gifts for guests and for traditional holidays. Thus, food produced in home gardens not only gained added value as gratification for the people’s effort but also performed important social and cultural functions. Occasionally, the produce surpluses were offered for sale to visitors of the villages, at local markets and, when organized, at local fests. Six of our participants regularly offered fresh produce (fruits, onion, and leafy greens) at the local farmers’ markets or to wholesalers who visited their villages. These endeavors also involved only surpluses. Garden produce was also exchanged among fellow villagers to ensure more diverse plant foods. In some cases, home gardens (5) served for the provisioning of guest houses by their owners, thus adding value to the tourist service and ensuring the authenticity of the “taste of place”. Food from home gardens was considered of high quality by their owners mostly because it corresponded to their expectations for tastes that have deep roots in their memories and traditions. It also strengthens the ties between generations and serves as a vector for transmission of gastronomic knowledge among them.
The importance of some of the widely distributed and well established garden food plants was celebrated at local festivals, an activity that has recently become well-known. Among many, particularly popular are the Kurtovo Konare Fest dedicated to local plant food diversity and horticultural traditions and the Festival of Smilyan Beans that celebrates a complex of bean varieties cultivated in the Upper Arda Valley in the Rhodope Mountains. These festivals demonstrate the local food diversity and gastronomic skills and have attracted a growing number of visitors for over a decade. They have become a central part in the development of Kurtovo Konare and Smilyan as tourist destinations.
