Butterfly Bush

Buddleia davidii, Butterfly Bush

The Buddleia plant is a genus of flowering plants and there are up to one hundred species on record. Most of these are shrubs with only a few being trees. Because the tree varieties can grow to over 30 feet, it is the shrub varieties that are more suitable for the average sized garden. Butterfly bushes (Buddleia davidii) have a prime place in butterfly gardens, and are particularly adept at attracting tiger swallowtails. But they also attract hummingbirds, making them must-haves for hummingbird gardens, too. And don't forget the bees: butterfly bushes will also attract the bees that will pollinate other plants in your garden.

Buddleia davidii produces woody stems, it behaves like a perennial and dies back close to the ground. And just like a perennial, it makes no difference to the plant. Simply cut back the dead stems in early spring, stand back and watch the plant explode with growth. Buddleia blooms on new wood, so its floral display is not diminished by its dieback behavior. In fact cutting Buddleia back benefits the blooming and overall plant habit. Even in the south where its wood remains alive, an annual spring trimming makes for a nicer plant, blooms from midsummer until frost.
