Kerria japonica 'Pleniflora'

Wreathed in rich-yellow, fully double 2" ?buttercups?, this graceful shrub (to 6') with its green stems is lovely in spring. S-PSh/M

Double Japanese Rose, or Kerria japonica 'Pleniflora' is a popular landscape specimen because of it flowers at a very young age, is fast to establish, and is deer resistant. Stems bloom very heavily in the spring before the leaves emerge, much like Forsythia but the flowers are pom-pom like and more attractive than Forsythia flowers. Plus, flowers will be produced throughout the entire growing season on the tips of new growth all the way until frost, making this one of the longest blooming shrubs available. Plants are quite cold hardy and will often still grow in protected areas in zone 3. If plants freeze back to the ground, they will sprout back from the roots and still bloom that season. Best propagated in winter as hardwood cuttings of new growth, or under mist using softwood cuttings in June. Plants are best pruned back in late spring or early summer. Flower buds for next spring develop starting in summer and persist until they bloom the following spring, so you want to prune early enough in summer that you don't reduce flowering. You can prune your plant all the way to the ground every few years, or just prune lightly to maintain a specific shape.

This lovely, old-fashion shrub has arching green stems to about 5-6' tall with double yellow, inch wide flowers in mid-spring. Its open, graceful habit works well in a woodland setting or mixed in with native plantings. Growth Rate medium, 6-12" annually

Double pompom flowers in great abundance and produced over an extended season this is an incredibly vigorous clone that benefits from a bit of pruning, left unwacked it will rapidly grow to 8' or more, despite it's somewhat gangly nature this is the showiest of the clones we grow.

A vigorous deciduous graceful shrub for sun to pt shade. Sharply toothed bright green leaves are covered in spring with large buttercup double golden yellow flowers. reblooms in late summer

Large double flowers appear in the spring like masses of tiny golden globes. Green stems in the winter are excellent for contrast with the red twigged dogwoods or other plants with ornamental winter bark. 4-5? in ten years. Awards: Award of Merit & Award Garden Merit from the Royal Horticultural Society. Recommended by: Garden Clubs of America, the United States National Arboretum.

Bright yellow, 1", double, pom pom like blooms are borne along arching green stems in mid to late spring. Spreads by suckers.

Interesting, free-flowering shrub; could be used more extensively. Borders, masses, facer plant to hide leggy specimens. Tough plant, seems to withstand considerable abuse. Flowers in early spring with double blooms then on and off sporadically all summer. Usually burns in full sun here in zone 7 but probably not in colder areas. Morning sun is great.
