Kerria japonica 'Shannon'

Light Requirements:
Kerria japonica ‘Shannon’ prefers partial shade to full shade. It thrives under the dappled canopy of tall trees or along the eastern side of structures where morning sun gives way to afternoon shelter. In cooler regions, it can tolerate more direct sun, but in the Deep South, protection from harsh afternoon rays is essential to prevent foliage scorch.

Soil Preferences:
This adaptable shrub prefers well-drained, loamy soil rich in organic matter. While tolerant of clay and sandy conditions, it performs best in moderately moist soils with consistent drainage. Mulching around the base helps retain moisture and protect its roots during summer heat or winter chill.

Watering:
Once established, ‘Shannon’ is fairly drought tolerant, though it appreciates occasional deep watering during prolonged dry spells. In its first year, maintain consistent moisture to help roots settle in.

Pruning:
Prune immediately after flowering in late spring. Remove any old or crossing canes at the base to promote new growth and preserve its graceful, arching form. Avoid heavy pruning in autumn or winter, as it may reduce the following season’s bloom. If rejuvenation is needed, the entire plant can be cut to the ground in early summer, and it will respond with vigorous new growth.

Landscape Uses:
Ideal for woodland gardens, shady borders, and naturalized plantings. Its cheerful spring flowers and graceful form pair beautifully with ferns, hellebores, and other shade-loving perennials.
