Caryopteris x clandonensis / Blue Mist Shrub

With soft gray-green foliage, light blue late summer flowers and rounded habit, it looks right at home in the perennial border. The famous variety ‘Longwood Blue’ has sky blue flowers. Another popular type, ‘Worcester Gold’, has yellow foliage and blue flowers. Bees and butterflies love them, but deer don’t — a happy combination.

The “x” in the name means it’s a hybrid of two different species, so it’s not actually indigenous to anywhere.


  • Flowers August and September.
  • Needs full sun or light shade.
  • Grows to 2-3′ high and wide.
  • Hardy in Zones 5-8.


  • Authorities describe it as “thriving on neglect.” Sounds about right. Consider it drought-tolerant.
  • Many gardeners cut it back in late winter to 12″ to promote vigorous growth, and I’m one of them.
