Blue-white starry flowers in large clusters weave an exquisite tapestry against the dark green foliage. Petals arch back to reveal prominent stamens that radiate in all directions glistening in the light. Vigorous upright habit is non-vining but can be tied to a trellis or allowed to sprawl and ramble through shrubs or grow as a pleasant billowy groundcover even in dry dappled shade. Blooms July – Sept.
Discovered here in Ohio, this spontaneous hybrid volunteered in the garden of Mrs. Elizabeth Prentiss of Cleveland in the 1930’s. Will quickly cover space under shrubs or cascade over a rock wall or down a slope.
