This shrub is tolerant of many soil textures, moisture conditions, and acid to alkaline pH if it is in full or nearly full sun. However, it requires ample moisture and some protection from midday to afteroon sun to flower at it's best. The shrub will keep its upright form as it grows, so little pruning is required. While shaping or pruning can be done at any time, pruning in late winter or early spring will minimize the loss of the emerging flower buds on the new growth. Pruning heavily in early spring or pruning back to 2-3 buds will produce fewer but larger flowers. It can be pruned to to create a single trunk small specimen tree. Transplanting should be done in the spring as the shrub takes some time to get established. Plant about 2'-3' apart for a single row hedge.

Rate of growth refers to the vertical increase in growth unless specified differently. Rate, as is true for size, is influenced by numerous variables such as soil, drainage, water, fertility, light, exposure, ad infinitum. The designation slow means the plant grows 12” or less per year; medium refers to 13 to 24” of growth per year; and fast to 25” or greater.Manual of Woody Landscape Plants, by Michael Dirr.
