Rhubarb: What Is this Vegetable?

Rhubarb is actually a plant belonging to the Polygonaceae family. It has a unique appearance and a fascinating history. While it is considered a vegetable in various parts of the world, certain regions of America refer to it as a fruit because it is mainly used as one in cooking.

Scientifically, rhubarb is a herbaceous perennial that has leaves growing off its thick rhizome’s top. It first appeared in the United Kingdom 400 years ago, and, due to its unique flavour, has since become one of the most highly valued foods. Its most commonly used parts are its leaf stalks, which are sometimes used in desserts or as an ingredient in various sweet delicacies.

Throughout the year, rhubarb is cultivated in various parts of the world. This is why it is widely available in almost every season. Rhubarbs grown in greenhouses are called hothouse rubharbs, which may be sweeter and a deeper red colour than traditional, externally-grown rhubarbs.

Fascinatingly enough, the stalks of the rhubarb are the only thing ready for consumption. This is because the triangular leaves of the plant have a staggeringly high oxalic acid content. This particular acid may cause severe illnesses in some people, a trait which resulted in the common misconception that rhubarb is poisonous. When the plants are subjected to extremely cold weather, this dangerous and perilous acid has a tendency to migrate into the stalk, so it’s important to store the vegetable in temperate to warm spaces which reflect its natural climate.
