Description

Many gardeners plant several butterfly bushes together, so they grow into a shrub-like clump with blooms in all the colors--purple, pink and white.

Butterfly Bush is a shrub-like plant that looks sort of like a compact lilac, grows quickly and blooms in mid-summer. But the name tells you all about it: Butterflies just can’t resist the flowers, and flock to the plants when they're in bloom.

The Magic: How the Butterfly Bush works: Buddleia or Butterfly Bush has been a sensation in American gardens for years, and no wonder. This plant is easy to grow, blooms profusely, and has that magical quality: Butterflies can’t resist it.

Here's why: It’s not just the pretty flowers that attract the butterflies, like any bright flower. Buddleias emit a special honey-scented fragrance that lures butterflies like a moth to a light, and then once there, they find the flowers super-rich in nectar.

A butterfly bush in the garden will often be seen with a mass of butterflies on the flowers, especially during hot sunny afternoons. Buddleias attract other insects too, like moths, and the reddish ones strongly attract hummingbirds. So it’s more than a name; it’s actually a botanical phenomenon. 

Planting & Care

Planting Instructions for Butterfly Bushes:

  1. Open the box immediately, protect from cold, and water each potted plant. Some of your butterfly bush plants may have new green growth and some may not. If you see no leaves, don't worry; this is normal. The roots in the pot are healthy and ready to grow in your garden.
  2. Plant as soon as you can. If your weather cooperates (above freezing), begin planting as soon as possible. If not, keep your butterfly bushes where they get some sun through a window, and keep them moist, not soggy.
  3. As you set out your potted butterfly bushes, dig to loosen the soil around and below the actual spot, and then set the rooted plant at the same level if was growing in the pot.
  4. Plant your butterfly bushes about 4-6' apart, depending on the variety.
    When you remove the plant from the pot, do not pull on the leaves or stems. Squeeze the pot a little and the roots and soil will slide out for you.Water well after planting, and continue to water at least every two weeks, depending on rainfall.
