Report an issue with this species
Corylus avellana is a deciduous shrub native to Europe and Western Asia, typically growing 3-8 meters tall. It produces edible hazelnuts and has historically been used in hedgerows and for coppiced wood. While valuable to wildlife like squirrels, it spreads readily by suckers requiring pruning and can be prone to pest problems.
