Buddleia 'Lochinch': Fragrant Lilac-Blue Butterfly Magnet

Buddleia 'Lochinch' – A Butterfly Bush Standout

'Lochinch' butterfly bush (Buddleia 'Lochinch') is a carefree deciduous shrub that lives up to its name—Butterflies swarm to its extremely fragrant lilac-blue flowers with orange eyes all summer long. A hybrid between B. davidii and B. fallowiana, it combines vigor with exceptional fragrance.

Growth & Bloom

Arching, mounded habit reaches 3–5 feet in one season (taller in the Deep South). The 8–12 inch flower spikes begin in late summer and continue until frost, blooming later than B. davidii cultivars. Excellent as a cut flower.

Care Requirements

Plant in fertile, well-drained soil in full sun. Cut back to the ground in late winter or early spring for vigorous new growth. Propagate via semi-ripe cuttings in summer or seed at 66–75°F in spring.

Potential Problems

Fungal leaf spots and dieback can occur. Watch for capsid bug, caterpillars, weevils, mullein moth, and spider mites.
