Dwarf butterfly bush
Planting areas: Zones 6, 7, 8 and 9
Size: 3 to 5 feet tall, 3 to 4 feet wide
Bloom season: Early summer to late fall
Exposure: Full sun to partial shade
Pruning needs: Remove spent flowers to prolong bloom. Cut back canes in late winter to promote fuller new spring growth.
Water needs: Medium to low; drought tolerant once established.
Snapshot: As its name indicates, the dwarf butterfly bush is a miniature version of its much larger cousins, which can tower 10 to 12 feet.
Like its full-sized counterpart, this compact perennial not only fits beautifully into small suburban landscapes but also serves as a magnet for bees, butterflies and hummingbirds. They’re attracted to the dwarf butterfly bush’s sweet nectar and dense, spike-like lavender flowers.
Although commonly called “butterfly bush,” buddleia varieties should not be confused with milkweed and butterfly weed, which are both members of the asclepias family. Milkweeds are the only plants that monarch butterfly larvae can eat, and therefore are critical to the species’ survival.
