Prairie Alum Root
Flowers on tall, hairy, leafless flowering stems (scapes) in open or dense terminal panicles. The flowers are greenish or yellowish green, sometimes tinged with red, small (just under ½ inch long),bell-shaped, the upper lobes longer than and drooping over the lower ones, with orange-tipped stamens slightly emerging from the flower. Blooms April–June. Leaves basal on long, hairy petioles, palmate, often deeply cleft with large teeth; 3–5 lobes, quite showy.
Similar species: There are 4 species of Heuchera in Missouri. Common alum root (H. americana) is absent from the northwest third of the state and parts of the Bootheel; it has smaller flowers and is common on bluffs and rocky woods. Small-flowered alum root (H. parviflora) grows on bluffs and rock outcrops in the Ozarks.; its leaves have rounded lobes. Maple-leaved alum root (H. villosa) is uncommon and known only from Shannon County.
