Heuchera merriami, or Alumroot, grows up to 10,000 feet elevation but it is hardy to only -10 F. The leaves are small, with scalloped edges, and form a low clump near the ground, while the flowering stalks rise up about six inches, with open clusters of delicate, creamy flowers. Alumroot is an excellent specimen for a rock garden and grows well in filtered or afternoon shade with typical garden water at lower elevations. In a garden this plant stands out when several plants are grouped together and the flowers are massed and appear as one showy cluster. Heuchera merriamii is perfect in a small, rock garden growing with Penstemon davidsonii, Penstemon rydbergii, Penstemon heterodoxus, Arnica parryi, Aster ascendens, Campanula rotundifolia, Eriogonum umbellatum, Geranium californicum, and Heuchera hirsutissima.
