Botanical Name

Plant Common Name

Alumroot, Palace Purple Alumroot

General Description

Palace purple alumroot, is an evergreen herbaceous perennial grown for its mounded clumps of glossy, greenish-purple maple-like leaves. The large leaves, which are beet red on their undersides, retain their color all year if given enough light. In late spring to early summer, tall stems topped with loose panicles of tiny greenish, creamy white flowers emerge from basal clumps. The flowers attract bees and hummingbirds. Alumroot is native to western North America, where it grows in fertile, moist but well-drained neutral soil.

This perennial grows best in sites with part sun and fertile, but well drained soil. It tolerates full sun only in cooler climates; in the desert, grow Palace Purple in full shade with good light. Purple palace alumroot is a carefree, long-lived perennial with minimal maintenance required. Remove the flower stalks when they finish blooming. Mulch annually to keep the rootstock covered, and eventually lift and replant the clump in late summer or early autumn. This alumroot looks great when planted in masses beneath trees, in mixed borders, or rock gardens; it can also be grown as a groundcover. Palace purple alumroot was named the 1991 Perennial Plant of the Year.
