The oval leaves are medium to dark green, have coarsely toothed edges and are fuzzy on top and downy underneath....

(European Filbert, Filbert, Hazelnut)

European filbert is an ornamental shrub to small tree that originates from its namesake. This plant is generally monoecious, which means that single plants have separate male and female flowers. Its conspicuous male flowers, which are drooping yellow catkins, bloom in late winter to early spring, before its leaves emerge. Tiny yellow female flowers appear at the same time and later generate hazelnut fruits. In fact, European filbert is the primary species grown commercially for hazelnuts. In the...
