Bluebeard
Caryopteris x clandonensis
A low, airy shrub that brightens late summer and fall with clouds of fragrant blue flowers when little else blooms, crowded by butterflies and bees, over aromatic leaves. It's drought tolerant and seldom touched by deer. Cut it back hard in late winter, since it blooms on new growth, and give it lean soil that drains.

Spacing for a hedge
VeraScape spaces plants so their grown canopies just touch. For Bluebeard, that’s about 2 ft apart, center to center.
Place a row in your own yard and VeraScape spaces them at their mature width, so you can see whether they’ll crowd the walk.
