Corylus colurna aka Turkish Filbert

Taxonomy

Corylus colurna, commonly known as the Turkish hazel or Turkish filbert, is a medium-sized deciduous tree native to southeast Europe, southwest Asia, and parts of northern India. With a symmetrical and conical habit, this tree features slightly lobed broadly-ovate leaves and pendulous yellow catkins that can reach a length of 8cm. It produces nuts that are held within a deeply fringed husk. Growing at a slow rate, Corylus colurna can reach heights of up to 20m (65ft) with a width of 7m (23ft). This tree is hardy in zone 5 in the UK and blooms from April to May, with the seeds ripening from September to October. Corylus colurna is a monoecious species, meaning it has individual flowers that are either male or female, but both can be found on the same plant. Wind acts as the pollinator for this self-fertile tree.

How to care for Turkish Filbert

Difficulty

Turkish Filbert presents a moderate level of care, which allows plant enthusiasts with some experience to expand their skills and knowledge.

Water

Turkish Filbert should be watered regularly, allowing the soil to dry out between waterings.

Soil

Turkish Filbert loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

Turkish Filbert thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Byzantine Filbert.

Toxicity

The toxicity level of this plant has not been officially confirmed by Ploi. If there is a possibility of ingestion of plant material with an uncertain toxicity by you, a family member, or a pet, it is advisable to seek the assistance of a medical professional.

Fertilizer

Repotting the Turkish Filbert is necessary either when it has doubled in size or once every year, whichever happens first. With fresh potting soil replenished annually, the plant will receive all the necessary nutrients, rendering the use of fertilizer unnecessary. Keep in mind that the source of a plant's energy is the sun, not fertilizer.

Region of origin

Turkish Filbert’s native range is S.E. Europe to W. Asia.
