Heuchera parviflora is a species of flowering plant in the saxifrage family known by the common names cave alumroot and littleflower alumroot. It is native to the eastern United States.
The Blackfoot Indians used pounded, wet roots of Heuchera parvifolia for rheumatism and sores, and an infusion of the roots as an eyewash.
Heuchera are hardy plants that survive punishing winters as far north as USDA plant hardiness zone 4, but they need a little help from you when temperatures drop below the freezing mark.
Heucheras grow very well in containers (ensure they have drain holes) and as far as care goes they can be treated as described above. The main concern will be keeping the soil moist. Be sure to water well in summer months but at the same time don't let autumn and winter rain water log the plants.
