Kerria japonica Pleniflora


Bachelor's Buttons

Amazing double pom-pom like yellow flowers in early spring

These are spring blooming plants with unique double yellow flowers. This deciduous plant has prominently veined, light green leaves.


The plants form a rather attractive shrubbery in shady places, besides being used as informal hedge plants, screens and pretty shrub borders.


These plants prefer well-drained, but moist fertile soil with full sun or partial shade.

The genus name honours William Kerr who collected this plant for the Royal Botanic Garden at Kew in the late 1700s to early 1800s.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
