18" tall x 15" wide. Heuchera sanguinea 'Firefly' (Coral Bells) is a western wildflower that has been bred and improved to give us one of our most popular garden perennials. The bright red flowers are held high on long thin wands over the tidy mounds of scalloped foliage. Heavy blooming in well-drained, compost enriched soil, flowering is prolonged by deadheading of faded flowering spikes. Best in part sun and shade in hot climates, but will do well in full sun at higher altitudes with cooler summer weather. Water regularly for the best show of flowers. (seed propagated).
