Butterfly bushes are carefree deciduous shrubs that are reliably fragrant and easy to grow. Butterflies swarm to their blooms all summer long. ‘Lochinch’ has extremely fragrant lilac-blue flowers with orange eyes. It is a cross between B. davidii and B. fallowiana . Its arching, mounded habit typically reaches 3 to 5 feet in one season, but can grow much taller in the deep South. The 8- to 12-inch-long flower spikes begin in late summer and bloom until frost, starting a little later than the B. davidii cultivars.
Noteworthy CharacteristicsGood cut flower. Very fragrant. Vigorous growth.
CareGrow in fertile, well-drained soil in full sun. Cut back to the ground in late winter or early spring.
PropagationRoot semi-ripe cuttings in summer or sow seed at 66° to 75°F in spring.
ProblemsFungal leaf spots and diebacks can occur. Buddleia are susceptible to capsid bug, caterpillars, weevils, mullein moth, and spider mites.
