Small-flowered Alumroot (Heuchera micrantha) is a graceful perennial native to the western United States, particularly thriving in rocky outcrops, forest edges, and shaded slopes. Its elegant foliage forms low mounds, while delicate spikes of tiny, bell-shaped white to pale pink flowers rise above in late spring and early summer. This species is particularly valued for its ornamental qualities and ecological contributions to shaded gardens and natural landscapes.

 

Small-flowered Alumroot supports a variety of pollinators, including native bees, small bumblebees, syrphid flies, and small butterflies that are attracted to its nectar-rich blooms. Its dense foliage also provides shelter for insects, amphibians, and other small creatures. Native to rocky, well-drained soils, it stabilizes slopes and enhances biodiversity in challenging environments, making it an excellent choice for erosion control and wildlife-friendly gardens.

 

This adaptable plant thrives in partial to full shade, preferring moist, well-drained soils but tolerating a range of conditions, including drought once established. Small-flowered Alumroot is easy to grow from seed, with germination enhanced by a 2-4 week period of cold stratification. Seeds can be surface sown in fall or early spring, with blooms typically appearing the following year.
