Description

When there is little else blooming in the garden in late summer and early fall, this flowering perennial shrub is there to delight us, and the butterflies. The common name Blue Mist refers to its fluffy, cloudlike flowers. ‘Longwood Blue’ features fragrant bright blue to lavender-blue nectar-rich flowers that the butterflies will flock to. This light airy shrub quickly reaches an average size 3 feet tall and wide with attractive grey-green leaves. A soothing and sensory charmer in smaller garden spaces or large containers or in groupings or as a colorful hedge in larger spaces. This beauty is tolerant of drought, resistant to pest and disease, and is seldom browsed by deer.

Landscape & Garden Uses

Growing to around 3 feet tall and wide, the ‘Longwood Blue’ Blue Mist Shrub is ideal for use as an accent, in groupings or as a hedge to add soothing color and texture in landscape borders and perennial gardens. It is also useful as a centerpiece in large containers. A fine addition to butterfly and hummingbird gardens, beneficial pollinator gardens, cottage gardens, fragrance gardens, blue theme gardens, and the Xeriscape (low water needs).

Suggested Spacing: 30″ for solid hedges or mass plantings; 6′ for space between

Cultural Preferences

Blue Mist Shrub is easy to grow in most any moist and loamy but well-drained soils of average fertility and full to mostly sun, however is very drought tolerant when established. Constantly soggy or wet soils can be problematic. It flowers on new growth so is best pruned if necessary in late winter or early spring, which will create more new growth resulting in more flowers. In cold climates below zone 6 the stems will die back to the ground with new growth emerging from the base of the plant in spring.
