Care level

While its tart stalks are famous in pies and jams, the real show happens in spring when enormous umbrella-like leaves unfurl from the ground, creating a dramatic tropical effect in temperate gardens. Each plant can produce up to 12 pounds of stalks per season, though the leaves should never be eaten as they contain high levels of oxalic acid.
