Bluebeard ‘Longwood Blue’ | Plant Profile

Bluebeard ‘Longwood Blue’ (Caryopteris x clandonensis) are fragrant, mound-forming, deciduous shrubs that are native to Pennsylvania. The bright blue flowers that cover the outside of the plant are highly fragrant and the most coveted aspect. The violet or blue flowers grow in clusters at the end of upright stems. The blooming season is comparatively long, lasting from July to September. Silver-gray oval leaves populate the shrub.

‘Longwood Blue’ prefers average fertility, medium moisture, well drained soils in full sun. Once established, these fragrant shrubs can tolerate some drought, but will not perform well in saturate soils.

These highly ornamental shrubs are often planted as low borders or in groups. They can be planted along fences, structures, or in parks. The late blooming flowers bring interest while other shrubs have already spent their flowers. The fragrant flowers attract bees and other pollinating insects, making them a perfect addition to a pollinator garden.


Bluebeard 'Longwood Blue' Characteristics

'Longwood Blue' are highly ornamental fragrant shrubs with an extended flowering season. They are coveted for the cloud forming lbue flowers that reach beyond the rest of the foliage. When touched, the pleasant aroma becomes even more obvious.

'Longwood Blue' can experience some vulnerability to the harsh Pennsylvania winters. The roots should survive with a thick layer of mulch for protection. The stems are not winter hardy and will die back in winter. Pruning and cutting hard stems to the ground is advised in early spring. Flowers bloom on new growth, so cutting back old foliage should not affect flowering.

There are few serious insect of disease issues that are common in 'Longwood Blue'. Crown and root rot may occur in poorly drained soils.
