Butterfly bushes (Buddleia or Buddleja) are large, fast-growing shrubs whose flowers are irresistible to butterflies. Buddleias are easy-care plants, but they’re invasive in some areas. Look for sterile cultivars which don’t set seed and therefore don’t run wild.
This statuesque plant adds strong architectural interest to your flower border and attracts butterflies by the dozen. Because perennial foliage usually declines after the plants bloom, choosing a late-season bloomer such as Joe-Pye weed ensures you have lush, beautiful foliage all season long. The variety called ‘Gateway,’ shown, reaches up to six feet in height.
