Rhubarb is a leafy vegetable that grows in early spring about the same time that spinach develops. The only edible portion are the leaf stems. See more about it below.

About Rhubarb:
The rhubarb petioles (leaf stems) in this photo are a deep red in color, but rhubarb is often sold when it is more greenish in color. We have not noticed much difference in the flavor, but we prefer the red because we believe it is more nutritious. Rhubarb is bitter tasting by itself, but great when cooked with fruit. Select rhubarb that is crisp and free of dried ends. See the nutritional chart below for raw rhubarb. We could not find any data for cooked rhubarb without sugar. If the rhubarb is cooked with other ingredients of a recipe, we would suspect that most of the nutritional value would remain in the finished preparation.
