Give your garden a nonstop burst of color with Buddleia davidii 'Butterfly Candy(R) Li'l Grape(TM)' (Butterfly Bush 'Butterfly Candy Li'l Grape'). This compact butterfly bush stays nicely sized while producing dense, purple flower spikes that can keep coming from late spring into fall when grown in bright sun. The sweetly fragrant blooms are a magnet for butterflies and hummingbirds, making it an easy choice for pollinator beds, mixed borders, and patio plantings.
Plant in full sun for the best flowering and a tight, bushy habit. Choose well-drained soil and water regularly the first season to help roots establish; once established, it handles short dry spells better, especially with a light layer of mulch to keep soil moisture even. Expect mature size around 24-36 inches tall, with a similar spread in good conditions.
Because butterfly bush flowers on new growth, prune in early spring before vigorous growth begins. Cut stems back to a framework to control height and encourage fresh shoots that will carry the season's blooms. Deadheading spent flower clusters can help keep the plant looking tidy and may encourage continued blooming. Feed lightly in spring with a balanced, slow-release fertilizer if your soil is lean.
In colder areas, stems may die back in winter, but plants can regrow and bloom on new shoots. Give it space for airflow, avoid waterlogged sites, and keep pruning tools clean. In some regions butterfly bush can self-seed; remove spent flowers before seed set if that is a concern where you garden.
