Corylus avellana 'Contorta' – Corkscrew hazel

View prices and availability
Strong shrub that grows to multi-stemmed tree with densely branching, round crown. The brown twigs are very twisted and winding and this is still highly visible in the older trunks. The matt green leaves are basically round to obovate, but these are also very curved and coiling, so that they appear almost misshapen. They have no significant autumn colours. The male catkins are already visible before winter, but open around late February. The combination with the twisted twigs gives the tree a remarkably graceful appearance. The small, red, female flowers are inconspicuous. The fruits ripen around September. Yields significantly less fruit than typical for the species. The root system is susceptible to suffocation. Can be used in any soil as long as it is adequately airy and drained.
Our trees can only be planted when they don't have any leaves. Due to the this we will start delivering again from noiembrie 2024.
