Companion Planting

Plants well with

American black elderberry

Sambucus canadensis

Both shrubs prefer similar conditions and their combined presence creates beneficial guild structure, attracting complementary beneficial insects and wildlife.

Allegheny blackberry

Rubus allegheniensis

Blackberries and hazelnut create complementary woodland edge guilds with different vertical layers, attracting diverse beneficial insects and wildlife.

American chestnut

Castanea dentata

Chestnut and hazelnut are compatible woodland understory species that support each other through mixed guild benefits and complementary root depths.

Notable Cultivars

Most American hazelnuts in cultivation are seed-grown or unnamed clones rather than named cultivars. Selection focuses on nut size and productivity rather than ornamental characteristics.
