American Alumroot grows wild in rocky open woods, in crevises and ledges of rocky outcrops and in rich, moist woods from Michigan & southeast Ontario into New England down to Georgia over to Louisiana to Nebraska. Its sort of maple-like, semi-evergreen leaves are variable in size and color of green to variegated to shades of purple. The tiny white bell-like flowers bloom on leafless stalks (scapes) in May-June. The flowers develop into tiny capsules with tiny lustrous seeds inside. This mother species is sold by some native plant nurseries. There are a number of cultivars from this species, plus hybrids with other Alumroots or Coralbells in many cultivars sold by any conventional nursery with a perennial section.
