Plant Common Name

Blue Mist Shrub, Blue Spirea, Bluebeard, Grand Bleu® Bluebeard

General Description

The patented bluebeard Grand Bleu® offers intense blue flowers in fall. This vigorous small flowering shrub is as tough and drought tolerant as it is pretty. The hybrid originates from a cross between the two Asian species Caryopteris incana and C. mongholica and was derived from an induced mutation of the popular cultivar ‘Heavenly Blue.’

The deciduous shrub has a particularly uniform mounding, rounded habit and becomes covered with many small dark green toothed leaves that have a minty scent if crushed. In the fall, the leafy stems become lined with many dense colorful whorls of flowers. These are intense violet-blue, draw pollinators in masses and are sweetly scented. The fruits are small, winged and have seeds that will readily sprout in the garden.

Plant bluebeard in sites with full to partial sun and average soil with good drainage. It is root-hardy to USDA Zone 5 where it will resprout from the ground in the spring. In warmer areas, it should be hard-pruned low to the ground after flowering to keep next year's growth compact and neat. It makes a nice accent plant in the mixed border and looks great planted in rows as a low ornamental summer hedge.
