Cloud Nine bestows plentiful, double flowers in marbled shades of pastel blue-purple on the landscape in early to late summer, with a second flush of blooms later in the season. This proliferation of 1-1½" blooms gives a very special look to beds or borders over a long period. The compact 16" plants have a tidy, mounded form and produce loads of weed-suppressing foliage throughout the growing season. Pollinator friendly and drought tolerant, Cloud Nine is a true gem in the garden.
