alumroot, coral bells Interesting Notes

The Perennial Plant Association's 1991 Perennial Plant of the Year®

Striking mahogany foliage contrasts beautifully with silver- or golden-leaved plants. Dainty, bell-shaped blooms are white to green on mahogany stems. An attractive accent in the garden or cut flower arrangement.

Large, maple-shaped leaves are rich purple-bronze on top, pinkish purple underneath; leaves turn bronze-green in high heat conditions. Creamy white flowers. - Darwin Perennials

Originally selected by Brian Halliwell, curator of the herbaceous and alpine collections at Kew Gardens, England.
