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 Pearl

How 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

Coral Bells requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Black Pearl will be sure to bring you many years of beauty and enjoyment.

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.
