  • Prefers rocky soil but is adaptable and easy to grow just about anywhere, in clay-loam, loam, or sandy soil.


Description

Richardson's alumroot is a neat, rounded plant with broad, basal leaves that grow in a rosette low to the ground. The flowers are not showy, ranging from inconspicuous green and cream colours to pink and purple, but the tall (up to 60 cm) stems provide a nice airy contrast to the leaves. The yellowish seed heads also provide visual interest throughout the summer. 

The leaves turn an eye-catching red in the late summer and fall, and stick around until the following year.

Alumroot is an extremely easy-to-grow, low maintenance plant that is adaptable to nearly any garden conditions, from sunny and dry to moist and shady.
