Heuchera 'Black Pearl' (also known as Alum Root) is a compact, mounding perennial prized for its striking foliage. Glossy jet-black leaves feature scalloped, ruffled edges and vivid rosy-purple undersides. Mature leaves may develop a subtle silver sheen. In midsummer, delicate white flowers with pink calyxes rise above the foliage, adding seasonal interest.

Grows best in an average to moist well-drained soil in partial sun. Newer cultivars are bred to tolerate more extreme growing conditions such as drought, heat, humidity, and exposure levels. Heuchera are very versatile and create an excellent colour contrast option in mass or as an individual accent perennial. Remove spent flowers from taller cultivars to keep a uniform appearance. When planting, it is important to note that the crown should remain slightly above the soil level to prevent stem rot. Root weevils are a common problem for coral bells.
