European hazel

Overview

European hazel is a large deciduous shrub native to Europe and western Asia. It spreads through suckers, forming thickets of multiple shoots. Both sexes of flower occur on the same plant: conspicuous male catkins and tiny female flowers appear on bare branches before the leaves.

The nuts develop inside short leafy husks, often in small clusters. When ripe in late summer they are released from those coverings. Birds, squirrels and field mice eat the nuts, while bees visit for pollen. The species is widely cultivated in Europe for hazelnut production.
