This attractive and fairly long-blooming shrub has small, round, pearl-like flower buds that open in sequence to pure white, five-petaled flowers. Foliage is medium green turning to a soft yellow fall color. Older bark peels off, similar to birch, adding winter interest.
This plant has some cultivated varieties. Go to list of cultivars.
