The Chaste Tree is a small deciduous tree or large shrub with large spikes (6 to 8 inches) of blue-violet flowers in early summer. Its flowers attract bees and butterflies when in bloom. It prefers to grow as a multi-trunk tree, but can be pruned to a single trunk.
This tree will tolerate dry conditions, but will perform better with light water. It can be planted in small or narrow areas where there is not room for a larger tree, and pruned to achieve the desired clearance and shading. For best appearance, prune after bloom.
