Care tips
This species thrives in full sun, requiring at least 6 hours of direct sunlight for optimal development. It needs regular watering, especially during dry spells, but is relatively drought-tolerant once established; avoid waterlogging. It prefers well-drained, fertile soils rich in organic matter, though it can grow in a variety of soil types. A common mistake is planting it in excessive shade, which results in leggy growth and poor flowering.
