CARYOPTERIS x cland. 'Dark Knight' - Single Plants
This offering is for single plants of this variety. These are growing in 2.5 inch containers.
Easily grown in average, medium, well-drained soil in full sun. Prefers loose loams. Tolerates some drought. Intolerant of wet, poorly-drained soils. Roots are winter hardy to USDA Zone 5, but top growth is only reliably hardy to USDA Zone 7. Consequently, plants are generally grown as shrubby, soft-wooded perennials north of USDA Zone 7 by pruning stems back hard each year in early spring. Regardless of pruning intentions, stems will often die to the ground in the cold winters of Zones 5 and 6, with roots surviving to push up new stems in spring. Even in warm winter climates where the stems usually survive winter, gardeners frequently still prune the plants back hard in early spring to promote vigorous new stem growth. Flowering is unaffected by spring pruning because plants bloom on new growth. Bluebeard (also commonly called blue spirea or blue mist) is a low-mounded, deciduous shrub that is valued for its aromatic foliage and late summer flowers which are said to resemble clouds of blue smoke or mist. Clandonensis hybrids typically produce about 18-30" of growth per year, so total shrub height (usually from 2-3') depends in large part upon the extent of winter dieback and/or the annual spring pruning. 'Dark Knight' features a profuse, shrub-covering bloom of fragrant, deep bluish-purple flowers in terminal and axillary clusters (cymes) from late summer into fall. Ovate to lance-shaped, dull green leaves (to 1.5" long) are silvery below. Foliage is aromatic when brushed with a hand. Flowers are very attractive to butterflies, bees and other beneficial insects. May be found sold under that name 'Black Knight'. Zones 5 to 9.
