For a garden that hums with life, Buddleia davidii, or Butterfly Bush, is a must-have. Known for its long, spiky clusters of fragrant purple, pink, or white flowers, this deciduous shrub attracts a variety of pollinators, especially butterflies, from summer into fall. Buddleia grows rapidly, reaching up to 10 feet tall and wide in ideal conditions, and thrives in full sun with well-drained soil. It’s an adaptable plant that tolerates a range of soil types and is highly drought-tolerant once established. Although it may die back in colder climates, it rebounds quickly when pruned in early spring, ensuring abundant blooms year after year.
