Corylus cornuta

Form: Oval, Pyramidal.

Corylus cornuta is a deciduous Shrub growing to 3 m .
It is hardy to zone 4. It is in flower from April to May, and the seeds ripen from September to October. The species is monoecious and is pollinated by Wind. The plant is self-fertile.
Suitable for: light , medium and heavy soils. Suitable pH: acid, neutral and basic soils and can grow in very alkaline soils.
It can grow in semi-shade or no shade. It prefers moist soil. The plant can tolerates strong winds but not maritime exposure.

Landscape Uses:Firewood, Specimen, 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. 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 5.8 to 7.5. Plants are fairly wind tolerant. Plants are hardy to about -30°c. They thrive in a short growing season. This species is occasionally cultivated for its edible seed in N. America but is of no value in Britain as a seed bearer. Plants can bear fruit in 5 - 6 years from seed. Members of this genus bear transplanting well and can be easily moved even when relatively large. Special Features:Not North American native, Inconspicuous flowers or blooms. The plant is heat tolerant in zones 7 through 5. .
At this temperature, many plants begin to suffer physiological damage. Heat Zones range from 1 to 12 .
For example Heat Zone. 11-1 indicates that the plant is heat tolerant in zones 11 through 1.) For polyculture design as well as the above-ground architecture information on the habit and root pattern is also useful and given here if available. A clumping plant, forming a colony from shoots away from the crown but with a limited spread . The root pattern is suckering with new plants from underground runners away from the plant .
