Heuchera cylindrica at Kew Garden
Heuchera cylindrica is a herbaceous, clump-forming perennial from the Saxifragaceae family of plants. It is also known as Poker Coral Bells, Poker Allumroot, Roundleaf Alumroot, or Coral Bells. It tolerates more extreme temperatures and dry winds. It is native to North America, the Western United States, and British Columbia. It was named after Johan Heinrich von Heucher (1677-1747), a German botanist. The foliage is lobed or toothed and usually round. Heuchera cylindrica flowers on erect leafless spikes that can grow as tall as 35in or 85cm. The flowers are yellow and appear in the summer.
Plant Heuchera cylindrica in the sun or partial shade in organically rich, humus-rich, moist soil that is also well-drained. In its native environment, it grows in rocky areas. It performs much better in full sun. Try not to let the soil dry down but never go soggy. In general, it is disease-free and pest-free but in cold climates, frost heaving the roots can occur and watch out for heuchera rust, bud eelworm, or vine weevils.
