The Story

Coral Bells are native Spirits that grow all over North America in different forms. Up until the 1990s, gardeners considered them to be nice garden plants, but nothing too spectacular. Then breeders began to make crosses, and exciting new Coral Bells in brilliant colors began to appear. The charge was led by talented plantsman Dan Heims of Terra Nova Nurseries in Canby, Oregon. Heims and his team developed this selection, too. The Terra Nova crew sought to produce a plant that was brighter than previous reds and that possessed good vigor. Fire Alarm was introduced to the public in 2012.

The Details

Flowers, too! Fire Alarm Coral Bells is grown primarily for its captivating red foliage, but its blooms are a nice bonus. In summer, tiny, airy white blossoms rise on slim stems, making a lovely accompaniment to the blazing leaves.

How to Grow

Most Coral Bells do best in morning sun, with shade during the hottest part of the day. Bright light will bring out the richest coloring in their foliage, but intense sun can scorch some varieties. Plant Fire Alarm in rich, organic, well-drained soil that is moist but never soggy. Trim off spent flower spikes if you find them unattractive. Fire Alarm is evergreen; clean up any winter-damaged foliage in early spring. Black vine weevils can be a problem in some areas. You can control them organically with beneficial nematodes if this is the case, or simply keep your Coral Bells in containers.
