Very good growing shrub. The flower stalks are large, perhaps up to 6-7" long. The marketing exaggerates on size of the florets themselves. They are not the size of a dime rather but are the same as other cultivars which is some pretty strong lying compared to the advertising. This aside I know if anyone had bought this plant wouldn't dig it out because of the lies. It is a good ornamenal and fragrant plant, however I dont feel this cultivar differs much from sixteen candles or the like.

Clethra - Vanilla Spice Summersweet

This North American native is a standout plant with attractive glossy, dark green leaves and extra large flowers. Vanilla Spice is a strong growing and a healthy shrub. The individual flowers are roughly the size of a dime, about twice the size of a typical Clethra. It has large spikes that are loaded with fragrant, pure white flowers in the late summer. There are few plants that offer such wonderful fragrance in the late summer. Butterflies and hummingbirds adore this plant. Excellent flowering shrub for landscapes, use it in perennial or shrub borders, and masses or groupings.
