Care tips
It thrives in full sun to partial shade, with well-drained soil that is moist but not waterlogged. Water regularly during dry spells, especially in its first year, but avoid overwatering which can lead to root rot. Average garden soil is sufficient, though it prefers slightly acidic to neutral pH. A common mistake to avoid is planting it in heavy, poorly draining soils, which will hinder its growth and flowering.
