Instead of a common perennial with showy leaves
Plant: Rhubarb for pies.
How to grow: Start bare-root plants in late winter or early spring; in zones 10 and 11, plant in fall as a cool-season annual. Plants reach 3 feet tall. (When harvesting, eat only the stalks; leaves are poisonous.) Best in Sunset climate zones A1–A3 and 1–11 but may do well in 14–24.
