Heuchera — 56 species

Heuchera — coral bells and alumroots — are North American woodland perennials grown as much for their striking mounded foliage in burgundy, caramel, silver, and green as for their wiry stems of small bell-shaped flowers. They adapt well indoors in bright, indirect light, though they tolerate part shade, and they prefer consistently moist, well-drained soil; soggy roots quickly cause rot. American alumroot and hairy alumroot are tougher in dry spells once established. The ASPCA lists Heuchera as non-toxic to cats, dogs, and horses, making the entire genus a reliably pet-safe choice for mixed plant collections.
