Additional Information

'Pleniflora' is a very popular cultivar of Japanese Kerria with its long lasting, bright yellow, double flowers that are nearly spherical, reminiscent of "pom-poms". Fairly adaptable to soils and microclimates, including considerable shade; best out of extremely sunny exposures. Occasionally winter-injured in the north, but otherwise relatively trouble-free. Suckers and spreads slowly. Needs occasional pruning to remove dead branches and renewal pruning to maintain form.
