Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water regularly when the top 2-3 cm of soil feels dry, especially during the growing season. Avoid overwatering, as Erysimum odoratum is susceptible to root rot. Reduce watering in winter when the plant is less active.
Ensure good drainage to prevent waterlogging.
Deadhead spent flowers regularly to encourage continuous blooming. Prune lightly after the main flowering period to maintain a compact shape and prevent the plant from becoming woody.
Remove any dead or diseased stems at any time of year.
Easily propagated from seed sown in spring or early autumn. Can also be grown from semi-ripe cuttings taken in summer. Seeds may require a period of cold stratification.
Cuttings should be rooted in a well-draining compost mixture.
Repot annually in spring, especially young plants, to provide fresh soil and space for root growth. Use a well-draining compost mix, such as a loam-based compost with added grit.
Avoid disturbing the root ball excessively.
