Heuchera villosa, the hairy alumroot, is a small evergreen perennial native to the Eastern United States. It is found only on rock outcrops, growing on cliffs and boulders.

Heuchera villosa is sometimes grown ornamentally, with some cultivars giving having a reddish leaf coloration.

There are two described varieties, which are sometimes considered distinct species.[1] They are:

  • Heuchera villosa var. macrorhiza - On calcareous substrates, primarily west of the Appalachian Mountains
  • Heuchera villosa var. villosa - On acidic substrates, primarily of the Appalachian Mountains and eastward
Variety macrorhiza, with broad, shallow leaf lobes and oblong inflorescence bracts
