About
Corylus avellana 'Heterophylla' is a deciduous shrub that typically reaches a height of around 6 meters. It features narrow, softly hairy leaves that are deeply lobed and turn a pale yellow in the autumn before they drop. In winter, the plant produces numerous yellow catkins, which bloom early in spring and later give way to a bounty of sizable, edible nuts that attract squirrels.
