✂️ Care

Water moderately during establishment, then reduce watering once the plant is well-rooted due to its drought tolerance. Regularly remove spent flowers to prolong blooming and encourage continuous production of delicate flowers.

Lightly prune after flowering to maintain a compact and vigorous shape. In autumn, cut back stems to the ground to promote vigorous regrowth in spring.
