Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water regularly, especially during establishment and dry periods. Aim for consistently moist, but not waterlogged, soil. Reduce watering in winter as growth slows.
Allow the top few centimeters of soil to dry out between waterings to prevent root rot.
Prune in late winter or early spring before new growth begins. Remove dead, damaged, or crossing branches. You can also prune to shape the plant and control its size. Hard pruning can rejuvenate older, overgrown shrubs.
Easily propagated from softwood cuttings taken in early summer. You can also propagate by division of established clumps in early spring or autumn. Seed propagation is possible but can be slow and less predictable.
Repot young plants every 1-2 years in spring to refresh soil and provide more space. Mature plants in the ground rarely need repotting. Choose a pot that is slightly larger than the current one with good drainage.
