Tiny white flowers in small flattened clusters (corymbs) cover the foliage in late spring. Birch-like, dark green leaves (to 1.5 inches long) are oval and sharply toothed. Foliage turns amazing shades of orange, red and purple in autumn. As an added bonus the flowers are attractive to butterflies.

It will even tolerate clay if the drainage is adequate. You will need to provide regular water to this small shrub to keep it looking its best through the summer.
