The butterfly bush, or summer lilac, is a shrub or small tree used as adornment in gardens that provides nectar for butterflies. Originating from warm regions, it is of the genus Buddleia davidii.
Description
The butterfly bush is a hedge plant with clusters of small, fragrant flowers that resemble lilac blooms. The cone-shaped petals range from 8 to 20 inches long. Butterflies, bees and hummingbirds are attracted to the nectar and brightly colored blooms.
History
According to an article in "Butterfly Gardner's Quarterly," the butterfly bush originated in Chile, although most species currently available come from China. The genus name Buddleia comes from a 17th-century botanist, the Rev. Adam Buddle, who brought the first butterfly bush to England in 1774.
Planting and Growth
Butterfly bushes grow well in a variety of climates, spread quickly and can range from 5 to 15 feet tall. According to Claire Dole in "Butterfly Gardner's Magazine," the growth form is disorderly, so bushes should be planted at least 6 feet apart. Butterfly bushes need at least six hours of direct sunlight and adequate water to thrive.
Maintenance
Butterfly bushes require little maintenance. Pruning dead petals will keep the plant in bloom longer. Horticulturist Gerald Klingaman of the University of Arkansas Agricultural Division suggests cutting down blooms each winter to regrow them from the ground. Growth and density will increase each year. Ideal bloom time is from Mid-July through winter.
Varieties
The Buddleia genus includes more than 100 species and varieties. Flower colors are primarily shades of blue and purple, but reds, pinks, yellows and whites are also common.
