Discussion
Kerria japonica is cultivated in central Europe and North America, particularly in the east, as a shade-tolerant ornamental shrub. The species persists long after cultivation and spreads mostly vegetatively, apparently only rarely spreading by seed. It is expected elsewhere. The cultivar 'Pleniflora' has multiple petals appearing as a yellow-orange rose.
