Cultivars/Varieties

'Aurora' - A newer selection that is gaining a foothold in American horticulture, this selection has a superior floral display. The clusters are larger with pink-white blooms that open from deep pink buds. The fragrance is very strong. The plant grows larger, to 8' tall.

'Compactum' - A very fine plant that was originally introduced by a Rhode Island nursery in 1953, this dwarf form offers fragrant spring blooms on a plant that seldom exceeds 3' tall and wide. The foliage is a healthy dark green and disease resistant.

'Cayuga' - This hybrid selection (with V. carlcephalum) was introduced by the U.S. National Arboretum and is considered a superior plant. It is a larger, dense grower that reaches 5' tall with reddish fall color. Early spring is greeted by white flowers arranged in globular cluster that emerge from pink buds.
