Roundleaf Alumroot

Roundleaf Alumroot is a versatile and durable native perennial found in rocky slopes, woodlands, and montane environments across the western United States and Canada. It forms attractive mounds of rounded, slightly toothed, semi-evergreen leaves, which vary in color from medium green to lightly marbled depending on local ecotypes.

In late spring to early summer, the plant sends up airy panicles of bell-shaped flowers held on slender stems that can reach 1–2 feet tall. These blooms may appear pale green, cream, or soft white, and attract a range of small native pollinators, including solitary bees, hoverflies, and tiny wasps. Though not a nectar powerhouse, Roundleaf Alumroot plays an important ecological role in supporting early insect activity in upland areas.

Highly valued in native and ornamental plantings alike, it’s deer-resistant, moderately drought-tolerant once established, and can be used in shaded rock gardens, woodland borders, or mass plantings for texture.

• Prefers well-drained soil; avoid heavy, wet clay.
• Tolerates part shade to full sun in cooler climates.
• Remove spent flower stalks to tidy up appearance.
• Divide every 3–4 years if clumps become woody or crowded.
• Mulch lightly in fall to protect crowns in colder zones.
