Overview
Rhubarb (Rheum × hybridum) is a perennial plant belonging to the Rosaceae family and is native to China and Russia. It thrives in full sun to partial shade with moist soil that can be light (sandy), medium, or heavy (clay). Rhubarb is hardy in zones 3-8 and reaches heights of about 1.5 meters with a width of 1 meter. This plant is commonly propagated through division and requires spacing of approximately 92 cm between plants. Known for its edible stem, rhubarb has been cultivated both for culinary use and traditional medicine. Its distinctive red or green stems are often used in desserts and jams, while the leaves are toxic due to high levels of oxalic acid. Rhubarb's ornamental value is also appreciated in gardens where it can add a striking presence with its large, glossy leaves.
