Heuchera cylindrica Douglas ex Hook.
Poker Heuchera, Roundleaf Alumroot
Saxifragaceae (Saxifrage Family)
USDA Symbol: HECY2
Leathery leaves, varying from ovate to broadly heart-shaped, on long stalks clustered at base of flower stalks; upper plant densely covered with glandular hairs, especially in narrow, greenish-yellowish flower cluster.
The dense narrow flower cluster and the very short petals (or their absence) help distinguish this species from several others in the genus. Alumroot species are variable, making identification of many plants difficult.
