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. Get all the details below!
