San Diego native plant gardeners take note: Heuchera sanguinea, commonly known as coral bells, no longer belongs in your plot.
The popular clump-forming perennial named for its bell-shaped flowers has been removed from the California Native Plant Society's database, which supports native plant gardeners and industry members.
"After reviewing Heuchera sanguinea, our team determined that it is not native to California, as its natural range is limited to Arizona and New Mexico," a representative for the group says in an email.
Dropping the species is not quite as simple as overthrowing San Diego's official flower, the non-native carnation, in favor of a native. That effort by the San Diego Bird Alliance and partners — awaiting a public vote this month before going to the city council — targets a genus that arose in mainly Europe and Asia.
Coral bells, on the other hand, were one of the first plants exported back to Europe in the 1600s by American explorers.
Fans of Heuchera sanguinea, with its often blood-red flowers, have options. "There are still 49 other Heuchera species and cultivars listed on Calscape."
California has around 15 native species and subspecies of the genus, which includes coral bells and alumroot. Jill of the Rocks and Island alumroot grow in the Channel Islands. Pink alumroot is found in the Sierras, Klamath region, and Southern California.
Rosada coral bells, an alumroot hybrid developed by the University of California-Davis arboretum, was used in irrigation trials in San Diego and other counties to study the best low-water plants for sustainable California landscapes. The "climate-ready" coral bells are on their "all stars" list for their toughness (surviving even inland San Diego).
Aside from being best adapted to local conditions, native plants help support local pollinators and insects. Research has shown that gardens with lots of non-native plants are a threat to the neighborhood's insect-eating birds.
