If you want a dramatic, fountain-like flowering shrub for pollinator color, Buddleia davidii 'Pink Cascade' (Butterfly Bush 'Pink Cascade') brings long, arching clusters of fragrant, soft-pink blooms that appear in summer and can continue into fall with regular deadheading.
Give it full sun for the heaviest bloom, but it will tolerate part shade. Plant it in well-drained soil and avoid sites that stay soggy, especially in winter. Once established, it handles periods of drought better than many flowering shrubs, though it looks best with occasional deep watering during extended dry spells.
Mature size is typically about 60-72 inches tall and about as wide, so plan on roughly 5-6 feet of space for its gracefully weeping habit. It pairs well with sunny borders and open garden beds where you can enjoy both the flowers and the steady stream of visiting butterflies and hummingbirds.
Because it blooms on new wood, you can prune it back hard in late winter or early spring to encourage vigorous new growth and abundant flowering. Remove spent flower clusters during the season to keep it tidy and help extend bloom. In colder areas it may die back and regrow from the base the next season, so wait for new growth before removing any stems you think are winter-damaged.
