Thanks to its three distinct plant geographies and rich climatic diversity, Turkey lies within one of the world’s most productive zones for beekeeping activities. Anatolian lands host thousands of plant taxa that are critical for colony development and sustainable honey production. This geographical richness allows bees to find nectar and pollen, their fundamental food sources, throughout a significant portion of the year. Efficiency in beekeeping is directly correlated with correctly identifying the local flora and strategically following flowering periods. Transporting colonies to regions with the most intense nectar flow significantly increases the honey yield obtained per hive. Honey plants attract bees through the sugar density of the nectar they secrete and the protein value of their pollen. Mastering the life cycles of these plants is the fundamental key to success in beekeeping.
Honey plants and their classifications
Plants used in beekeeping are examined in different categories based on the type of nutrients they provide, their lifespans, and the habitats in which they grow. This classification enables beekeepers to create seasonal plans and proactively meet the nutritional needs of their colonies. Plants are fundamentally divided into nectar sources, pollen sources, and species that provide both nutrients. For beekeepers, this distinction serves as a guide for managing periods targeted for honey harvest versus those targeted for increasing the colony population.
The classification of flora is the single most important factor determining the quality and quantity of production. While species with high nectar yields are indispensable for commercial honey production, plants rich in pollen play a vital role in brood development and preparation for winter. A significant portion of the approximately twelve thousand plant taxa recorded in Turkey’s flora are visited by bees. When classifying, the sugar concentration of the plant’s nectar, the duration of the flowering period, and its geographical prevalence are taken into account. This spectrum, extending from annual herbaceous plants to centenarian trees, guarantees the sustainability of beekeeping.
Classification criteria for Turkey’s honey plant flora
Evaluating the vegetation across the country in terms of beekeeping potential relies on specific scientific and practical criteria. The first criterion is the nectar secretion potential of the plant and the sugar ratio contained within this nectar; bees generally prefer to collect nectar with a sugar concentration between 20% and 50%. Sources below this ratio in terms of energy efficiency are visited less frequently by bees or are completely ignored. The second important criterion is the length of the flowering period.
A plant that flowers for a short time, regardless of how intense its nectar yield is, may not provide enough time for the colony to build up stock. An ideal nectar source should remain in bloom for at least 20 to 25 days, offering bees a sufficient window to work. The third criterion is the plant’s adaptation to altitude and climate conditions. The fact that different species are dominant in areas ranging from sea level up to 2500 meters highlights this criterion in determining migratory beekeeping routes. Additionally, the nutritional value of pollen grains is a determining factor in classification.
Honey plant groups and dominant species by region
The Anatolian geography is located at the intersection of the Euro-Siberian, Mediterranean, and Irano-Turanian phytogeographical regions, and each region hosts unique honey plants. The Euro-Siberian region, which includes the Black Sea coastline, is characterized by species that thrive in humid and temperate climates. Plants in tree and shrub forms, such as chestnut, linden, and rhododendron, are dominant in this belt. In particular, chestnut trees are the main pillar of regional beekeeping due to the intense nectar flow they provide at the beginning of June.
In the Mediterranean and Aegean regions, maquis formations and drought-resistant plants are at the forefront. Carob, heather, and citrus species are among the most productive nectar sources in this region. In the Irano-Turanian region, covering Central and Eastern Anatolia, broad steppe plants are dominant. Species such as astragalus, thyme, and sainfoin are plants that have adapted to the harsh continental climate and yield high-quality honey. Regional dominant species, such as the Turkish red pine forests in the Muğla region, determine the honey production identity of that area and increase its commercial value.
Cultivated plants
Plants grown in large fields for agricultural production that are also rich nectar sources constitute the backbone of industrial beekeeping. Since monoculture farming is generally practiced with these plants, they allow bees to collect high amounts of nectar within a short distance while expending less energy. For beekeepers, areas planted with cultivated crops are strategic fields where honey yield is predictable and logistical planning is facilitated. The integrated execution of agriculture and beekeeping activities is a model that mutually enhances productivity.
While farmers ensure better pollination and high yields for their products, beekeepers obtain strong colonies and full honeycombs. Plants such as sunflower, cotton, canola, safflower, and sainfoin lead the category of cultivated plants in Turkey. The flowering times of these plants create an uninterrupted food chain for bees by balancing the periods when the wild flora in nature weakens. Honey obtained from cultivated plants provides an advantage in marketing thanks to its standard taste profile and homogeneous structure. However, agricultural pesticide applications in these areas pose a serious risk that must be carefully managed for the health of the colonies.
Prominent cultivated honey plants in Turkish beekeeping
The first and most common cultivated plant that comes to mind regarding the beekeeping sector in Turkey is the sunflower. Sunflower, planted on hundreds of thousands of decares of land, especially in the Thrace, Central Anatolia, and Marmara regions, meets a significant portion of the country’s honey production with the abundant nectar it offers in July. While the flowering period in a sunflower field lasts an average of 15 to 20 days, this period can extend up to 45 days in regions where staggered planting is practiced. Sunflower honey is known for its unique bright yellow color and its tendency to crystallize quickly.
The cotton plant is also a vital source for beekeepers in the Aegean, Mediterranean, and Southeastern Anatolia regions. Cotton offers a rich feast to bees by secreting nectar not only from its flowers but also from the nectar glands under its leaves. The flowering period of cotton can reach up to 50 days, which translates to a long-term honey harvest. Canola, the cultivation of which has increased in recent years, is an excellent pollen and nectar source that ensures colonies strengthen rapidly in early spring. Canola pollen encourages brood rearing in bees emerging from winter due to its high protein content.
Planting time and honey yield planning for cultivated honey plants
It is essential for beekeepers to closely follow regional planting calendars and plant phenology to benefit maximally from cultivated plants. The nectar secretion capacity of plants varies greatly according to planting time, soil moisture, and seasonal temperature values. For example, canola is generally planted in the autumn months, spends the winter in rosette form, and blooms in March or April. This early flowering is a critical advantage that accelerates the spring development of bees.
Forage crops such as sainfoin and alfalfa are included in the beekeeping calendar according to their mowing times. Alfalfa thrives in temperatures of 25 °C and above for nectar production, and nectar flow increases with irrigation. Since farmers mowing alfalfa before the full flowering period can lead to nectar loss, communication between the beekeeper and the farmer is crucial. Allowing flowering at a rate of 10% to 20% preserves the nutritional value of the forage while ensuring that bees can benefit from it. Beekeepers must plan such details in advance and keep their colonies in the field during the most productive period.
Wild plants growing in nature
Plants that grow in their natural habitats without human intervention, generally called “wildflowers,” are the true architects of the aromatic richness and quality of Turkish honey. Pastures, plateaus, forest clearings, and roadsides are the richest areas in terms of biodiversity and offer bees a clean feeding ground away from pesticides. The diversity of these plants makes polyfloral (multi-flower) honey production possible while enriching the vitamin and mineral content of the honey. Natural flora is indispensable for the sustainability of the ecosystem.
Natural plants are generally resilient species that have adapted to harsh environmental conditions such as drought, frost, and wind. Compared to cultivated plants, these plants are more resistant to climatic stresses and can provide a more stable nectar flow. Endemic honey plants growing especially on high-altitude plateaus prepare the ground for the emergence of products with very high added value and world renown, such as Anzer honey. These species growing spontaneously in nature are also quite rich in secondary metabolites that support the immune system of bees. For beekeepers, these virgin areas are the most valuable regions where they can produce safely.
Most productive honey plant species growing wild in pastures
The most characteristic and productive plant of Turkey’s vast pastures and steppes is undoubtedly the astragalus (geven). Astragalus, which has more than two thousand species—many of which are endemic—shows wide distribution on the high plateaus of Central Anatolia and Eastern Anatolia. Astragalus honey sees intense demand from consumers due to its very light color, mild aroma, and late crystallization. Astragalus species bloom in late May and June, and depending on species diversity, the nectar flow can last for 20 to 30 days.
Thyme species are also among the indispensable nectar sources of pastures. Known for its sharp scent and strong antiseptic properties, thyme is among the most important plants that increase the healing quality of honey. Species such as mountain thyme and ball thyme secrete productive nectar even on rocky and calcareous lands. Additionally, herbaceous plants such as mullein, chicory, deadnettle, and poppy enrich the pasture flora. Chicory, in particular, offers bees the first fresh pollen and nectar of the day with its blue flowers that open in the early morning hours and close towards noon.

Regions with high wild honey plant density in migratory beekeeping
Migratory beekeepers move their hives from coastal areas where flowering begins to high altitudes that are cooler and flowery in the summer months to extend the honey production season. In this operation, regions where natural vegetation is dense and diverse serve as strategic stopping points. While spring starts very early in the Mediterranean coastal belt, flowering continues until July and August in the high mountain meadows of Eastern Anatolia. This time interval gains the beekeeper an active harvest period of approximately 4 months.
The plateaus of Erzurum, Kars, Ardahan, and Artvin are at the top of the routes most preferred by beekeepers in mid-summer, boasting a thousand and one kinds of wildflowers. The number of plant taxa per square meter in these regions is very high, and the risk of agricultural pollution is minimal. The sections of the Taurus Mountains at 1500 meters and above offer similar floral richness. Mountain mint, sage, and wild sainfoin found in the plateau flora accumulate more intense aromas thanks to the temperature difference between night and day brought by the high altitude. This situation directly raises the quality parameters of the produced honey.
Trees and shrubs
During hot summer days when annual herbaceous plants dry up or their nectar yield drops, trees and shrubs that can draw water from the soil with their deep root systems serve as a lifeline for bees. Forest ecosystems not only provide nectar for flower honey but also create the necessary foundation for honeydew honey production. Tree-sourced honey generally has a structure that is darker in color, rich in minerals, and crystallizes late. The presence of trees and shrubs in beekeeping is a great assurance in terms of the continuity and diversity of production.
Thanks to their vertical growth characteristics, trees have the capacity to host many more flowers per unit area compared to herbaceous plants. An adult linden, chestnut, or acacia tree can offer a nectar potential equivalent to a large pasture area on its own, thanks to the hundreds of thousands of flowers it bears. Additionally, forest areas allow bees to work in more suitable microclimate conditions by protecting hives from harsh winds and the scorching sun. Turkey’s rich forest assets include nectar-bearing trees such as chestnut, linden, acacia, and eucalyptus, as well as important honeydew honey sources such as pine and oak.
High honey-yielding tree and shrub species in Turkey
The Turkish red pine is accepted as the reference source worldwide for honeydew honey production. Specifically in the red pine forests of the Muğla, Aydın, and İzmir regions, the Marchalina hellenica insect processes the sap of the tree and leaves a sweet secretion, which bees collect and turn into pine honey. Turkey meets a massive portion—approximately 90%—of the world’s pine honey needs. This form of production depends on the life cycle of the insect, not the flowering of the plant, unlike flower honey.
Among nectar-source trees, chestnut ranks in the top tier. Chestnut forests in the Black Sea, Marmara, and Aegean regions yield chestnut honey, which has a bitter taste and strong antioxidant properties, from their cream-colored flowers that open in June. Acacia trees (false acacia) are also an important source, especially in the valley floors in Thrace and Eastern Anatolia. Acacia nectar yields a honey that is quite clear and fluid like water. Heather (püren), which grows in shrub form, is a critical plant that blooms in autumn and allows bees to make their final stocks before entering the winter cluster.
Honey flow management with honey trees in forest and coastal regions
Carrying out beekeeping activities in forest interiors and coastal regions requires the correct management of moisture balance and local air currents. Since forest areas are generally more humid, the maturation of honey inside the hive and the reduction of its water content mean extra energy expenditure for the bees. Placing hives in clearings that receive the morning sun, where air circulation is not obstructed, facilitates this process. In coastal strips, eucalyptus and citrus trees provide early spring and late autumn nectar in regions open to the sea effect.
Beekeepers must be extremely careful in the Black Sea forests where plants known as “mad honey” and capable of showing toxic effects, such as rhododendron, are dense. In these regions, harvest timing carries vital importance to keep the mixing of the poisonous grayanotoxin substance into the honey under control. In linden forests, the flowering period is quite short, lasting approximately 10 to 15 days; therefore, beekeepers need to adjust their timing very precisely. Rain falling during the flowering period can wash away the nectar in linden flowers, so weather monitoring is the key to success in forest beekeeping.
Plants that are valuable nectar sources and produce high-quality honey for beekeeping
Some plant species not only produce nectar but enter the “super honey plants” class with the quality, abundance, and continuity of the nectar they secrete. These species are specially planted in fields by beekeepers, or the areas where they are found in nature are taken under protection. These plants, which have very high nectar yields, maximize the amount of honey harvested per hive while reducing unit costs for beekeepers. Quality and aromatic honey production is a process too sensitive to be left to chance and begins with the selection of the right plant population.
Plants in this special category generally have a long flowering period and high sugar concentration. Bees visit these plants with a greater appetite and frequency compared to other ordinary sources. In-hive activity and comb-building speed increase visibly during these periods. Plants such as lavender, phacelia, lemon balm, and thyme are the most popular members of this elite group. The propagation of these plants provides great benefits not only for honey production but also for erosion control and visual landscape arrangements. High-yielding honey plants are the most fundamental natural capital that increases the profitability of beekeeping.
Principal species providing high nectar yield and quality honey
Phacelia (Phacelia tanacetifolia) is a nectar plant specially bred for the beekeeping sector and is widely preferred worldwide. A one-hectare phacelia field can provide a honey yield between 600 kg and 1000 kg under suitable climate and maintenance conditions, which is an extraordinary figure. Its flowers are in purple and lilac tones, producing a very high amount of nectar and quality pollen. The long flowering period, lasting approximately 6 to 8 weeks, offers the beekeeper a guaranteed and fruitful harvest opportunity.
Lavender is also a very precious plant grown for both its valuable essential oil and its unique honey. Lavender gardens concentrated in the Isparta and Burdur regions become the most frequented point for bees in July. Lavender honey is accepted as a very pleasant-smelling, light, gourmet product and has a high market value. Additionally, sage species, which are among medicinal and aromatic plants, are among the plants with the richest nectar sacs. The anatomical structure of sage flowers allows the bee to reach the nectar easily, and it continues to secrete nectar even in dry periods. These plants possess natural components that prolong the crystallization time of honey and increase its shelf life.
Prominent honey plants and honey characters in different climate zones
Each climate zone of Turkey hosts different vegetation that puts its own signature on the character, color, and aroma of the produced honey. In regions where a continental climate prevails, the high temperature difference between night and day causes plants to undergo stress and produce more intense aroma and sugar to protect themselves. Honey from these regions is generally sharp-sweet, thick in consistency, and quick to crystallize. In temperate climate zones, plants stay in vegetation for a longer time, which ensures the production of lighter, delicate, and soft-drinking honey.
For example, rhododendron honey grown in the misty and humid climate of the Black Sea is known for its unique bitter taste and dark amber color. In the Mediterranean climate, honey obtained from citrus orchards is distinguished by its refreshing aroma of orange blossoms and its light yellow color. Honey obtained from thorny plants grown in the hot and dry climate of Southeastern Anatolia is a very thick product that can remain durable for a long time without spoiling. Each plant’s nectar secretion threshold occurs at different temperature values; for example, while sainfoin gives the best yield around 20 °C, the cotton plant needs higher temperatures to secrete nectar. This rich diversity ensures that Turkish honey forms one of the widest flavor maps in the world.
