bluebeard, blue mist shrub Interesting Notes

Flowers are borne in tight clusters that encircle one side of the stem. This characteristic gave rise to its common name 'Bluebeard'.

Flowering begins in early August and persists for at least 8 weeks. Blooms occur on new growth and range from powder blue, through lavender to purple, depending on the cultivar. Cut flowers make a long lasting indoor show.

Deer do not eat aromatic plants or plants that have silver foliage. Because Caryopteris is very fragrant and has silvery leaves, deer leave it alone. It also has few insect or disease problems.

Caryopteris 'Longwood Blue' Growing and Maintenance Tips

Caryopteris needs full sun, and a light, well-drained soil. It flowers on new growth, so prune in early spring to ensure heavy flowering. It is somewhat tolerant of drought, but will not survive in saturated soils. Propagate by softwood terminal cuttings. Best used as a specimen, in foundation plantings or in perennial borders for late season color.
