What does rhubarb look like?

Rhubarb is a herbaceous perennial found in Rheum species and hybrids; it is also a member of the Polygonaceae family.

It spreads by means of short, thick rhizomes. Rhubarb’s fleshy and edible stalks are a fantastic culinary addition, according to gardeners.

This is common in the United States and Europe. However, in Asia, it is primarily used for medicinal purposes. Because of the high levels of oxalic acid and other compounds such as throne glycosides in their large triangular leaves, they are inedible.

Rhubarb flowers are tiny and form large leafy rose-red or greenish-white inflorescences. Gardeners consider the plant to be primarily a vegetable, but it also serves the culinary use of fruit.

Their stalks come in a variety of colors, with the most common being red or pink. Rhubarb has a sour flavor, and most gardeners prepare it with other ingredients such as sugar and use it in desserts.

Rhubarb grows best in cooler temperatures that are less than 5 degrees Celsius. When fast growth is stimulated in the spring, it emerges from dormancy. It thrives in summer temperatures of less than 23 degrees Celsius, which promotes vegetative growth.
