Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly in winter when the plant is dormant.
Ensure good drainage to prevent waterlogged roots, which can lead to rot. Overwatering is more detrimental than slight underwatering.
Prune back dead or spent flower stalks in late autumn or early spring to maintain a tidy appearance. Remove any diseased or damaged foliage promptly.
Heavy pruning is generally not required, but can be done after flowering to shape the plant if necessary.
Propagate by division in early spring before new growth begins. Carefully separate clumps of roots and replant them immediately.
Alternatively, seeds can be sown in autumn or spring, but may require stratification and germination can be erratic. Cuttings are less common.
Repot established plants every 2-3 years, or when they become root-bound. The best time to repot is in early spring before the growing season commences.
Use a well-draining potting mix, such as a mix of loam, sand, and compost.
