Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water new plants regularly until established. Mature plants are moderately drought-tolerant but perform best with consistent moisture, especially during flowering. Avoid overwatering, which can lead to root rot.
Prune after flowering to encourage a bushier habit and prevent excessive seeding. Remove spent flower stalks to improve appearance and direct energy into new growth. Light pruning can be done anytime to shape the plant.
Easily grown from seed sown in autumn or early spring. Seeds may benefit from scarification or a period of cold stratification. Cuttings can be taken from semi-hardwood in summer.
Young plants can be repotted annually or biennially in spring. Choose a pot only slightly larger than the current one. Mature plants are best left undisturbed in the garden as they dislike root disturbance.
