The 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.
