Rheum palmatum
Ornamental rhubarb
Polygonaceae
Deciduous, Perennials
RHEUMThe rhubarbs are stately plants, good focal points in well-watered perennial borders or at woodland edges. The large leaves arise directly from stout rhizomes; flowering stalks produce smaller leaves and prominent bracts. Blossoms are individually inconspicuous but are massed in tall, branching, plumy clusters, making a great show in late spring or early summer. Plant usually grow 4 to 10 ft. high and wide.
Grows best in deep, organically enriched soil.

Leaves of R. p. tanguticum are less deeply cut than those of the species and often tinted purple; flowers may be white, pink, or red.
