Watering, pruning, propagation, and repotting details from plant data
Water consistently during the growing season, ensuring the soil does not become waterlogged. Allow the top inch of soil to dry out between waterings.
Prune back in late winter or early spring to encourage bushier growth and remove any dead or damaged stems. Deadheading spent flowers can promote further blooming.
Easily propagated from seed sown in spring, or by division of clumps in early spring. Cuttings can also be taken in summer.
Repot container-grown plants every 2-3 years in spring, or when they become root-bound. Use a fresh, well-draining potting mix.
