The Chinese Chaste Tree is considered to be one of the best pollinator plants. In mid-summer, it flowers for four consecutive weeks and the honeybees and butterflies swarm to drink its sweet nectar. This aromatic shrub produces long chains of tiny, fragrant, bluish-lavender flowers that appear in the heat of summer. Since it blooms on new wood, it can be pruned to the ground in early spring to stimulate new leaf growth.
