Fountain Buddleia, Butterfly Bush, Summer Lilac
Buddleia alternifolia is not specific as to soil type, but prepare soil thoroughly before planting — its most important requirement. If planting more than one, space 15 to 18 feet apart.
Water during long, hot, dry spells to prolong the growing season. Unlike B. davidii, this plant does not die back to the roots each year; it flowers on year-old wood, so prune sparingly (thinning some of the older branches) after flowering has been completed.
