Turkish Filbert, Turkish Hazelnut Corylus colurna
* Corylus colurna is widely cultivated as an ornamental tree in Europe and North America. It is very tolerant of difficult growing conditions in urban situations, which has increased its popularity in civic planting schemes in recent decades. It has gained the Royal Horticultural Society's Award of Garden Merit. 
* The nuts are edible, but their small size (smaller than Common Hazel nuts) and very hard, thick nut shell (3 mm thick) makes them of little or no commercial value. Corylus colurna is however important in commercial hazelnut orchards, as it does not sucker, making it the ideal rootstock on which to graft the nut-bearing Common Hazel cultivars. 
* An impressive, handsome tree of pyramidal form; usually short trunked and low-branching; dark green, sometimes leathery leaves; pest free; likes full sun, hot summers, cold winters; drought tolerant when established; a potential street tree.
* An easily grown plant, it succeeds in most soils, but is in general more productive of seeds when grown on soils of moderate fertility. 
* The seed is eaten raw or cooked. Rich in oil. As nice a flavour as C. avellana, the common hazel nut. The seed ripens in mid to late autumn and will probably need to be protected from squirrels. When kept in a cool place, and not shelled, the seed should store for at least 12 months. An edible oil is obtained from the seed.

Corylus colurna (Turkish hazel) is a tree native to southeast Europe and southwest Asia, from the Balkans through northern Turkey to northern Iran. It is the largest species of hazel, reaching 25 m (82 ft) tall, with a stout trunk up to 1.5 m (4 ft 11 in) in diameter; the crown is slender and conical in young trees, becoming broader with age. The bark is pale grey-buff, with a thick, corky texture. The leaves are deciduous, rounded, 6–15 cm long and 5–13 cm across, softly hairy on both surfaces, and with a coarsely double-serrate to shallowly lobed margin.
The flowers are produced very early in spring before the leaves, and are monoecious, with single-sex catkins; the male pale yellow and 5–10 cm long, the female very small and largely concealed in the buds, with only the bright red 1–3 mm long styles visible. The fruit is a nut 1–2 cm long, surrounded by a thick, softly spiny and bristly involucre (husk) 3 cm diameter, which encloses all but the tip of the nut; the nuts are borne in tight clusters of 3-8 together, with the involucres fused at the base.
Corylus Colurna is a deciduous Tree growing to 20 m (65ft) by 7 m (23ft). 
It is hardy to zone 5. It is in flower from Apr to May, and the seeds ripen from Sep to October. The flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and are pollinated by Wind.The plant is self-fertile. 
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very alkaline soils.
It can grow in semi-shade (light woodland) or no shade. It prefers moist soil and can tolerate drought. The plant can tolerates strong winds but not maritime exposure.

Cultivation details                                         
An easily grown plant, it succeeds in most soils, but is in general more productive of seeds when grown on soils of moderate fertility. It does less well in rich heavy soils or poor ones. Does well in a loamy soil. Very suitable for an alkaline soil, but it dislikes very acid soils. Tolerates a pH in the range 5.3 to 7.3. Once established, this is a very drought resistant tree. It does not produce suckers. Plants are fairly wind tolerant. A very ornamental tree. Members of this genus bear transplanting well and can be easily moved even when relatively large. The Turkish hazel is occasionally cultivated for its edible seed. This species is also useful in hybridizing with C. avellana in order to develop superior fruiting cultivars.
Seed - best sown as soon as it is harvested in autumn in a cold frame. Germinates in late winter or spring. Stored seed should be pre-soaked in warm water for 48 hours and then given 2 weeks warm followed by 3 - 4 months cold stratification. Germinates in 1 - 6 months at 20°c. When large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame or sheltered place outdoors for their first winter. Plant them out into their permanent positions in late spring or early summer. Layering in autumn. Easy, it takes about 6 months.
Growing Info:
Scarification:Soak in water, let stand in water for 24 hours.
Stratification:cold stratify for 180 days.
Germination:sow seed 3/4" deep, tamp the soil, mulch the seed bed.
Other: fall sowing in mulched beds is preferred to artificial stratification
