GENUS INDEX

GENUS CODE: CORYL
GENUS SCIENTIFIC: Corylus
GENUS AUTHORITY: L.

GENUS SUMMARY: A genus of about 15-18 species, shrubs and trees, of temperate regions of the Northern Hemisphere. Eurasian species of this genus, C. avellana Linnaeus and C. maxima P. Miller, are the sources of commercial filberts or hazelnuts. They are sometimes cultivated in North America, especially in the Pacific Northwest. Our wild species are also excellent eating, but wild animals, especially squirrels, usually harvest them before they are ripe.

HORTICULTURAL
Plant Sale Text: American hazelnut is a suckering shrub that is a good landscape plant with lots of wildlife value. The suckers can be removed to limit its spread. One of the first plants to bloom (in early February, long before the leaves emerge), American hazelnut produces drooping catkins of male flowers and diminutive hot pink female flowers. At least two hazelnut shrubs are needed for nuts. Its small edible hazelnuts are fun to eat if you can get to them before the other critters do. Commonly found along stream banks. The Corylus genus supports up to 124 species of lepidoptera.
