Easily grown in average, medium, well-drained soil in full sun. Prefers loose loams. Tolerates some drought. Intolerant of wet, poorly-drained soils. 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. Flowers are very attractive to butterflies, bees and other beneficial insects.
No serious insect or disease problems. Crowns may rot in wet, poorly-drained soils.
Perennial borders. Shrub borders. Very effective in large groups or massed. Also effective as a low hedge. Valued for its late summer to fall flowers when few other shrubs are in bloom.
