About
Corylus avellana 'Twister' is a deciduous shrub reaching approximately 1.5 meters in height, notable for its uniquely twisted and contorted branches. The plant features heart-shaped, serrated leaves that are a mid-green hue, transitioning to yellow as autumn arrives. In late winter and early spring, it produces hanging yellow catkins, which are followed by edible nuts that mature in the fall.
