Heuchera

This perennial is commonly called “Coral Bells” due to the bell shape of its flowers. The other common name for this genus is Alumroot, which refers to the medicinal use of this plant as an astringent for bleeding wounds. This genus of plants is comprised of more than 50 different species, and they are hardy in zones 3 to 9, depending on the species and cultivar. Coral bells are perennials native to the Russian Far East, Canada, Mexico, and the United States. If you want to add bold colors to your garden, Heuchera’s might be just the plant you wish to.

These showy plants are grown for their leaf color, which ranges from yellow to purple to brown and has various shades in between. Coral bells have white to pink flowers that bloom in June and continue through the growing season. Be sure to deadhead the spent flowers to encourage a longer bloom time. Depending on the cultivar, these perennials can be grown in the sun or shade, but they will develop their best leaf color in the sun. Coral bells must be divided regularly every three to four years; otherwise, they can be a relatively short-lived perennial.

This perennial has relatively few disease or insect issues; however, leaf scorch can become an issue during hot, dry weather if the plants are planted in full sun. Some varieties can get powdery mildew; however, if adequate airflow is provided, it is rarely a problem. Coral bells are not particularly aggressive spreaders and can be crowded out by more aggressive plants. These plants grow well as edge plants in perennial borders or clustered in groups throughout a planting.
