Care tips
It prefers full sun to partial shade for optimal flowering, though it tolerates some shade. It needs well-drained, sandy to loamy soil, and is quite drought-tolerant once established, watering moderately during dry periods. Avoid heavy, waterlogged soils, as this can lead to root rot. Light pruning after flowering helps maintain a compact shape and encourages new growth.
