This plant thrives in full sun to partial shade and prefers well-drained, fertile soil. Water regularly, especially during dry spells, but avoid waterlogging. Prune back after flowering to maintain a tidy appearance and encourage bushier growth. In late fall, cut back the stems to ground level to prepare for winter. This plant is known for its vibrant blue flowers and attractive foliage, making it a standout in any garden setting. Regular care and attention will ensure its healthy growth and beautiful display.
