Family: Verbena Family (Verbenaceae)
Native Habitat: None- Hybrid of horticultural origin
 

Caryopteris x clandonensis is a great little hybrid shrub that is especially valuable for its late summer bloom. The original hybrid was raised in England in the early 1900's and since then many different varieties have been named. 'Sunshine Bleu' is a new English introduction that features bright, sunny-yellow foliage and a compact habit. The rich anethyst-blue flowers begin in late summer and continue until frost. This is a terrific butterfly plant. It is literally covered with butterflies on sunny summer and fall days.

Here in Zone 5, Caryopteris is sometimes a "die-back" shrub, depending upon the severity of the winter. The branches will die back to the crown in our coldest winters. Since it quickly regrows and blooms only on new wood, simply prune back to live wood in spring, stand back, and enjoy the coming show.

Habit & Growth Rate: Fast growing to 2 or 3 ft. high and wide.
Landscape Uses: Shrub border, mixed border, foundation plantings. Deer resistant. Attracts butterflies.
Hardiness: Zone 5 to 9. In Zone 5 sometimes behaves as a "die back" shrub and will die down to the crown in severe winters.
Culture: Easy. Full sun to light shade. Average garden soil. Prune down to live wood in spring. Will quickly regrow. Blooms only on new wood.
