Other Comments:

Although drought-tolerant, this shrub/small tree may benefit from a few deep, thorough soakings during extremely dry periods. When young, it tends to be multi-trunked, so if a tree form is desired, pruning is required. Very briefly deciduous. Although the range extends further north, it is best used in landscaping where temperatures do not drop below 20 degrees F.
