Corylus colurna Turkish hazel, Turkish filbert

A big tree with a straight, upright trunk and a wide ovoid, later often wide conical crown. This trunk gets a ridged, corky bark at an early stage. Branches too, have a soft corky bark. The leaf is wide and obovate with a double serrated margin. It is woolly haired. The inflorescence shows thick, up to 12 cm long, male catkins that hang down gracefully and inconspicuous reddish female flowers. They appear well before the leaves. The edible nuts are surrounded by capriciously grown glandular husks and are circa 2 cm across. C. colurna has a deep-rooting root system. It is a very strong tree that is little susceptible to diseases. It is drought tolerant and it also withstands hard surfaces well.
Our trees can only be planted when they don't have any leaves. Due to the this we will start delivering again from November 2025.
