Water Saving Tip:

Replace turf with groundcovers, trees, and shrubs. If you have areas where no one uses the grass, patches that do not grow well, or a turf area too small to water without runoff, consider replacing the turf with water-efficient landscaping.

  • Description

  • Notes

This kerria has the same upward, arching habit as the species, and the same bright green wood. The flowers, though are double-petaled, and sometimes nearly pom-pom-like. Grows about 8 to 10 feet tall and wide. Very well suited to a cottage or country-styled garden.
Grow in loamy, well-drained soil in part to full shade. Though it can grow in full sun, the flowers will fade quickly and the leaves will look parched and scorched by summer. Blooms on previous years wood, so prune after flowering, either selectively or to renovate (see Guides).
