'Fire Alarm' Coral Bells is a villosa-macrantha cross, so it copes well with our East Coast summer conditions. The leaves are a vivid red in the spring and fall, with more brownish red tones in the heat of summer. The flowers are delicate and ivory white, held above the remarkable foliage in late spring. Heuchera 'Fire Alarm' is a stand out in both woodland gardens and shade containers. Semi-evergreen.
