Culture
Easily grown in average, medium moisture, well-drained soils in full sun. Becomes weedy and sparse with diminished flowering performance if not grown in full sun. Does poorly in wet, poorly draining conditions. Will adapt to clay soil if properly amended. In USDA Zones 5 and 6, this plant will often die to the ground in winter and therefore is often grown as a herbaceous perennial. Even if plants do not die to the ground in winter, they usually grow more vigorously, produce superior flowers and maintain a better shape if cut close to the ground in late winter each year. Removal of spent flower spikes during the growing season may encourage additional bloom.
Noteworthy Characteristics
Buddleja is a genus of about 100 species of mainly shrubs but also some trees and climbers. They are native to Asia, Africa and North and South America. Commonly called butterfly bush, they are very attractive to butterflies and other pollinators.
Genus name honors the Reverend Adam Buddle (1660-1715), English botanist and vicar of Farmbridge in Essex.
The genus name is frequently listed today as Buddleia. However, Linnaeus named the genus Buddleja (pronounced with a silent “j”) which is still considered to be the proper spelling (first name survives) according to the International Code of Botanical Nomenclature.
Common name refers to its attractiveness to butterflies.
'Miss Molly' is a hybrid butterfly bush resulting from a cross between Buddleja 'Attraction' and B. 'Miss Ruby'. Mature plants will reach 4-5' tall with a 5-6' spread and a semi-compact, well-branched growth habit. The bottlebrush-shaped, 4" long, terminal inflorescences emerge from mid-summer through to frost and are densely packed with small, magenta-red, tubular flowers. This plant is protected by patent number PP23425.
Problems
No serious insect or disease problems. Nematodes can be troublesome in the southern United States. Rabbits tend to avoid this plant. This plant can spread readily by seed and is considered invasive in New Zealand, the United Kingdom, and certain parts of the United States and Canada. Check local laws and invasive plant resources before adding this plant to your landscape.
Uses
Provides attractive summer to early fall flowers when few other shrubs are in bloom. Grow in borders, cottage gardens, rose gardens or butterfly gardens. Can be massed for use as an informal hedge. Popular fresh cut flower.
