Coral bells (Heuchera Americana) are the world’s perennial coleus. First, these plants came in soft colors with small, insignificant flowers. Now they are available in a wide range of colors, with some varieties explicitly cultivated for their flower masses.
And they are also extremely low-maintenance. Also commonly known as alumroot, coral bells are clump-forming perennials native to North America and are found in somewhat dry locations in rocky forests and along cliff ledges and crevices.
The genus Heuchera includes 35 to 50 species. Usually, it features a basal cluster of heart-shaped leaves 12 to 15 inches high, with long petioles (3 to 5 inches wide).
The small, greenish-white flowers in airy, open panicles are borne on slender, thread-like stems extending well above the mound of leaves, typically 18-24 inches high in late spring and early summer.
