Heuchera, commonly referred to as Coral Bells, is a perennial plant renowned for its vibrant foliage and delicate, bell-shaped flowers. With numerous species and hybrids, Heuchera comes in a spectacular array of colors and patterns, ranging from lime green to deep purple. This versatility makes it an excellent choice for adding texture and contrast to garden borders, rock gardens, and containers.
Native to North America, Heuchera is a member of the Saxifragaceae family and thrives in various climates and soil types. Its foliage forms a neat basal mound, from which graceful flower stalks emerge in late spring to early summer. The small, colorful flowers attract hummingbirds and butterflies, adding a touch of movement and life to the garden.
In addition to its aesthetic appeal, Heuchera is appreciated for its hardiness and low-maintenance nature. Whether planted en masse or as a standalone specimen, it provides year-round interest with evergreen or semi-evergreen foliage in milder climates. Its adaptability to different growing conditions makes it a popular plant among gardeners of all skill levels.

Heuchera Care
Caring for Heuchera is relatively straightforward, making it a delightful choice for both novice and seasoned gardeners. While adaptable to various conditions, Heuchera thrives in well-drained soil with good organic matter. It appreciates consistent moisture but resists both drought and humidity to some extent.
Regular mulching with organic material helps retain soil moisture and keeps the roots cool, especially in hot climates. Care should be taken not to bury the crown of the plant, as this may lead to rot. Selecting the right location based on specific hybrid or species requirements for sun and soil will ensure a thriving and attractive plant.
Light Requirement for Heuchera
Heuchera prefers part shade to full sun, depending on the specific variety and climate. In hot areas, afternoon shade is beneficial, while in cooler regions, more sun may be tolerated.
Soil Requirements for Heuchera
Heuchera grows best in well-drained, fertile soil rich in organic matter. It can adapt to various soil types but prefers a slightly acidic to neutral pH.
Water Requirements for Heuchera
Heuchera needs regular watering, especially in the first year of planting. Once established, it can tolerate some drought but benefits from consistent moisture. Overwatering or waterlogged soil should be avoided to prevent root rot.
Temperature and Humidity
Heuchera is adaptable to different temperatures and can tolerate both cold and heat. Providing mulch in winter in colder zones helps protect the roots. Humidity is generally not a concern, but proper spacing and airflow prevent potential diseases.
Fertilizer
A slow-release, balanced fertilizer applied in early spring promotes vigorous growth. Over-fertilizing should be avoided, as it may lead to weak, leggy growth.
Pruning Heuchera
Pruning Heuchera mainly involves removing any dead or damaged leaves and spent flower stalks. Cutting back the foliage in early spring can encourage fresh growth.
Propagating Heuchera
Heuchera can be propagated by division in early spring or fall. Dividing the plant every 3-4 years rejuvenates it and maintains its vigor.
How To Grow Heuchera From Seed
Growing Heuchera from seed can be a lengthy process. Seeds should be sown in a cold frame in fall or indoors in early spring. Germination may take several weeks, and seedlings should be transplanted when large enough to handle.
Common Pests & Plant Diseases
Aphids
Control with insecticidal soap or natural predators like ladybugs.
Rust
Remove affected leaves and apply fungicide if necessary.
Common Problems With Heuchera
Leaf Scorch
This may occur due to too much sun. Relocate the plant to a shadier spot or provide protection during hot periods.
Crown Rot
Caused by planting too deeply or waterlogged soil. Planting at the correct depth and providing well-drained soil will prevent this issue.
Pro Tips
