Care tips
It thrives in full sun for optimal flowering, though it tolerates some partial shade. It requires well-drained, fertile, and slightly acidic to neutral soil; watering should be regular during dry periods, especially in the first few years. Avoid waterlogging, as it is susceptible to root rot. Pruning is minimal, primarily for shaping or removing dead branches after flowering.
