Care tips
It prefers full sun to light partial shade and well-drained soil of moderate to low fertility. It tolerates drought once established, but appreciates regular watering in dry climates or during flowering. Avoid waterlogging, as it is prone to root rot in overly moist soils. To promote continuous blooming and compact growth, it is advisable to deadhead spent flowers.
