What is it and how do I care for it? The butterfly bush, or Buddleia davidii, is a deciduous shrub that reaches a height of about 10 feet and has wonderful, somewhat fragrant flowers during the summer. Its flowers resemble those of the Lilac and are especially attractive to butterflies and hummingbirds.

The narrow cone shaped flowers are usually pink, purple, or white; there is also a most interesting butterscotch yellow variety called Buddleia globosa.

The Buddleia is an easy care shrub that requires average well drained soil and performs best in full sun. Since it can reach a height of 10’ it is best at the back of the border; its arching branches make a graceful backdrop for tall summer perennials. Buddleias are also excellent in mass plantings. Try planting them in groups of three or consider using them as a garden screen.

A question I hear frequently about Buddleias is, “When do I prune them?” Prune in early winter or spring. I recommend you cut the shrub back to about two feet and while you’re at it, remove any extra thick old growth. A vigorous pruning will ensure a healthy shrub. In early spring apply a slow release organic fertilizer and a thin layer of organic matter. It takes a lot of energy to produce the beautiful blooms that attract butterflies and hummingbirds like a magnet so feeding is very important.

Other plants that attract butterflies with their nectar include monarda, scabiosa, yarrow, lupine, verbena boneriensis, and herbs such as parsley, dill and fennel.
