Roundleaf Alumroot (Heuchera cylindrica) is a unique heuchera native to the western United States that stands out for it's preference for full sun conditions, making it one of the rare coral bells suitable for sunny garden areas! Although this alumroot prefers the sun, it still does well in dappled and part shade conditions, offering finely textured beauty with its soft, round, scalloped leaves and tall, airy spikes of creamy white flowers. Blooming in late spring to early summer for a few weeks, and possibly again later in the season, especially if the spent blooms are removed, this native perennial adds vertical interest without overpowering neighboring plants. The foliage forms tidy mounds that persist through much of the year, lending structure and subtle charm even when not in bloom. Roundleaf Alumroot is not considered a Utah native, but populations exist just minutes over the Utah/Idaho border. Use Roundleaf Alumroot in rock gardens, the edge of woodland gardens, north or east-facing garden beds and borders, or as a graceful filler among rocks and boulders. It is an easy plant to incorporate into more formal native designs due to its tidy habit.
