Rhubarb is a big, leafy plant, growing 2-3 feet wide and tall. It is grown for its leaf stalks, but makes a beautiful, ornamental plant, especially the red and yellow varieties. Many people prefer the red varieties for their taste and tenderness, although the green varieties tend to be a bit more productive than the red. Only the stalks are edible. The leaves themselves are toxic and are removed at harvesting. The leaves contain a substance called oxalic acid crystals, which are toxic and can result in poisoning. Rhubarb damaged by frost may become inedible. If the stems are not firm and upright, don’t eat them. Frost damage can cause the oxalic acid crystals to move into the stalks. You can compost rhubarb leaves, even though they are slightly toxic if ingested. The oxalic acid crystals dissipate in the soil long before they are absorbed by other plants. Rhubarb does best in cooler climates, since it requires temperatures below 40 F., to break the dormancy and stimulate bud growth. Rhubarb can be grown as an annual in warmer areas that get some winter cold if you start seeds in the late summer/fall and plant out early the following spring. But too much heat causes rhubarb to have thin stalks and leaves
