The chaste tree is a beautiful little deciduous tree or large shrub with a showy summertime flower display. The leaves are 3-4 in (7.6-10 cm) in diameter with 5 to 7 fingerlike leaflets. Also called sage tree, the foliage is likewise aromatic and is typically grey-green to dark green above and lighter on the undersides. The leaves also bear a striking resemblance to those of the infamous marijuana or hemp (Cannabis spp.) plant which provides yet another common name, hemp tree. When in bloom, due to the similarity of the flowers, the chaste tree is sometimes mistaken for butterfly bush (Buddleia). The chaste tree is a sprawling plant that grows 10-20 ft (3-6 m) and about as wide. Branched flower clusters are produced on new wood in late spring and early summer in a great flush that makes the tree look like a hazy purple cloud. It continues to bloom sporadically until early fall. Not only is the tree strikingly beautiful when in full bloom, but it is also fragrant and attracts pollinating bees and hummingbirds make hungry visits. Flowers are followed by a fleshy fruit that contains four seeds that are sometimes used as seasoning, similar to black pepper (monk's pepper is another of this species' common names). Flower color ranges from violet to blue to deep purple.
