Lo & Behold® Purple Haze Butterfly Bush

Lo & Behold® ‘Purple Haze’ is a low, spreading hybrid butterfly bush with fragrant purple-blue flowers and horizontal branches. Proven Winners lists a mature height of 2–3 feet and spread of 3–3.5 feet, with flowering from midsummer until frost. This groundcover-like habit distinguishes it from upright butterfly bush cultivars. ## Form and placement Use Purple Haze near a sunny border edge, in mass plantings, or where its arching branches can spread without covering smaller neighbors. The breeder lists green foliage, full sun, well-drained soil, and USDA zones 5–9. The published mature dimensions are ranges; allow 2–3 feet of height and 3–3.5 feet of spread for its horizontal branching. ## Growing conditions Choose a sunny site with good drainage. Provide consistent water while the plant establishes, then adapt irrigation to soil and weather; the breeder's drought-tolerance label does not mean a new shrub can go without water. Proven Winners reports that this named cultivar passed sterility testing, but that claim is specific to Purple Haze and should not be generalized to all Buddleja.

In spring, remove winter-damaged stems and prune only as needed to manage spread. Leave enough space for the wider branching habit and check local guidance for butterfly bush before planting.
