Kirengeshoma palmata Koreana Group

Kirengeshoma palmata Koreana Group



About this cultivar:

Krengeshoma palmata Koreana Group is a first-rate foliage plant, forming an exotic-looking, upright clump of toothed green maple-shaped leaves. Flowers appear in late summer as lemon-yellow bells, flaring open and held at the top of the stems. Normally used in shade-gardens, in our garden we grow ours in full sun. A bit taller and has slightly bigger flowers than the normal palmata, tho I can barel tell the difference unless they are right beside each other. In 2012 this was awarded the RHS AGM, but the species wasn't!?!

About this genus:

Kirengeshoma (kir-en-ge-sho-ma) is a genus containing two species of plants in the Hydrangea family (Hydrangeaceae). Kirengeshoma palmata was described by Yatabe in 1890 and Kirengeshoma palmata Koreana Group by Nakai in 1935. Both are clump-forming perennials native to Eastern Asia, with sycamore-like palmate leaves and nodding, waxy yellow flowers on slender stalks, growing in shady environments. They are grown as garden plants in temperate regions of the world.

They love moist woodland type soil and are thus thought of as woodland plants, however they will tolerate a full sun if they have enough moisture; not a problem on these islands! They can be slow to establish and are one of the few late-flowering woodland perennials. We actually grow ours in full sun!

Looks good with Rodgersia, Hydrangea, Tricyrtis, Gentiana, Aconitum, Hostas, Ferns, Astilbe; shade-overs.
