About
Corylus avellana 'Rotblättrige Zellernuss' is a vigorous large shrub or small tree, typically growing to a height and spread of 3 to 4 metres. Its branches have a graceful arching habit. The leaves start out as reddish-brown, transitioning to a brownish-green as the season progresses. In spring and summer, this variety produces red-brown catkins, which are succeeded by brown fruits in the autumn.
