Buddleia alternifolia 'Argentea'

Alternate-leaved Butterfly Bush

Plant Type:


Buddleia alternifolia 'Argentea' - A big, fast growing wild-haired shrub with lots of branches, many decumbent, creating a large fountain as in Addams' Family Cousin It. Foliage is gray-green. Purple axillary flower clusters erupt up and down stems making extra-long strands of solid or nearly solid purple. Fountain Butterfly Bush is undeniably fantastic in bloom. And as the common name implies it will draw those glorious winged miracles. Stems are cloaked in gray-tinged glabrous, lanceolate leaves providing a soft demeanor. 'Argentea' offers a substantial contrasting element to other companions when out of flower as part of a wildlife hedgerow, a screen or backdrop to a larger perennial garden. This easy-natured shrub originates in Kansu, China. Three-quarters to full sun in fertile, draining soil. If pruning is desired then accomplish this soon after flowering so that new stems will develop and harden-off in time for winter. Those new stems will carry next year's flowers. Established potted silver Alternate-leaved Butterfly Bush from cutting.
