Quick Overview:

The newest addition to the popular MONARCH® Butterfly Bush collection! ‘Blue Knight’ forms a dense clump of minty green leaves. Incredibly long, 10-12”, outward-facing flower panicles open light lavender purple and deepen to blue-purple with age. The new and the aged flowers appear on the panicles at the same time, giving the flower an interesting two-tone effect. This plant has incredible flower coverage, giving you quite the performance when it starts its first flush of blooms in late summer.

Description

Easily grown in average, medium moisture, well-drained soils in full sun. Becomes weedy and sparse with diminished flowering performance if not grown in full sun. Does poorly in wet conditions. In USDA Zones 5 and 6, this plant will often die to the ground in winter and therefore is often grown therein in the manner of an herbaceous perennial. Even if plants do not die to the ground in winter, they often grow more vigorously, produce superior flowers and maintain better shape if cut close to the ground in late winter each year. Prompt removal of spent flower spikes during the growing season will usually encourage continued bloom until frost.
