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.
'Pink Micro Chip' is a dwarf butterfly bush selection that features 6" long, panicles of small, fragrant, magenta-pink, tubular flowers. This cultivar was selected from seed-grown plants produced by crossing Buddleja 'Lilac Chip' and B. 'Miss Molly'. Mature plants will reach up to 2' tall with a similar spread. The male flowers of 'Pink Micro Chip' lack stamens and do not produce pollen while the female flowers are nearly sterile with seed-set potentially possible under very rare circumstances. Plant patent number PP26547 applies to this cultivar.
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.
'Pink Micro Chip' is essentially sterile and considered less invasive than other butterfly bush selections. Care should still be taken to weigh the costs and benefits of adding this plant to the landscape, particularly in areas where this plant is problematic.
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. Popular fresh cut flower.
