Heuchera sanguinea aka Coral Bells
Taxonomy
Heuchera sanguinea, commonly known as coral bells, is a clump-forming perennial herb native to the US states of Arizona and New Mexico, and to northern Mexico. The plant produces a basal foliage mound that can reach up to 10 inches tall and has evergreen foliage in warm winter climates. The Latin specific epithet sanguinea means blood-red, which refers to the color of the plant's deep pink to red, sweetly fragrant, bell-shaped flowers that bloom from late spring to early summer. The flowers can attract bees and hummingbirds and may continue to bloom through summer to early fall if faded flowers are regularly deadheaded. The rounded, cordate-based basal leaves have 5-7 slightly toothed, triangular pointed lobes and are borne on pubescent petioles up to 5 inches long. Heuchera sanguinea is primarily native to cliffs, hills, and alpine areas. The plant belongs to the Heuchera genus, and the genus name honors Johann Heinrich von Heucher, a physician, botanist, and medicinal plant expert at Wittenberg University in Germany. There are several commercially available cultivars of coral bells. As a houseplant, coral bells need regular watering and do best in long-lasting, direct light less than 1 foot from a window. They prefer well-draining soil and do not require fertilizers if they are repotted each time they double in size.
Common names
Coral Bells, Red Coalbells, Korau Zvanii (Lvl), Black PearlHow to care for Coral Bells
Difficulty
With a bit of knowledge and dedication, you can successfully care for Coral Bells, making it a rewarding choice for those seeking a moderate challenge.
Water
Coral Bells should be watered regularly, allowing the soil to dry out between waterings.
Soil
Coral Bells loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.
Lighting
To ensure optimal growth, the Coral Bells prefers bright indirect light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.
Dormancy
During the wintertime, it is common for Coral Bells plants to go dormant and their growth rate may slow down. Therefore, the amount of waterings should be spaced out more.

Toxicity
Coral Bells is not known to cause harm to humans or pets.
Fertilizer
The Coral Bells should be repotted either when it doubles in size or annually, whichever comes first. Providing new potting soil with all the vital nutrients annually is enough to support the growth of the plant, and thus, there is no need for fertilizer. Remember that plants derive their energy from the sun, not fertilizer.
Growth-pattern
New growth will sprout from the top of the plant as it grows upwards.
Region of origin
Coral Bells’s native range is South-western N. America - S. Arizona, N. Mexico.
