Buddleia davidii 'Black Knight' Buddleia davidii 'Black Knight'
(Butterfly bush, Summer lilac) Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Butterfly bushes are carefree deciduous shrubs that are reliably fragrant and easy to grow. Butterflies swarm to their blooms all summer long. 'Black Knight' has deep purple-blue, almost black, flowers in elongated clusters on arching branches to 10 feet tall if not cut back, and half that size if cut back. The blooms come from early summer to first frost. The foliage is willow-like and grayish green.
Vitex agnus-castus var. latifolia Vitex agnus-castus var. latifolia
(Chaste tree) (2 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Chaste tree is a southern favorite beginning to gain favor across the country. Whether left to grow as a large, multistemmed shrub or cut back annually for a more compact look, this selection is a winner. Fine, lacy leaves are glossy and green. Bright blue flower panicles begin to form in early summer and continue through the heat of the season and into fall. This is a reasonably cold-hardy, deer-resistant woody plant, and while V. agnus-castus is typically considered a Zone 7 plant, the variety latifolia can be grown in Zone 6 and even in southern areas of Zone 5.
