Rheum palmatum, commonly known as Chinese Rhubarb, is a deciduous perennial herb native to the mountainous regions and grassy slopes of Central and Western China, Vietnam, and Tibet. It can reach up to 2.5 m (8.2 ft) in height and width, featuring large, palmate leaves that provide a lush, tropical appearance. The plant produces tall panicles of small, reddish-pink flowers in early summer, which are quite showy and can add a dramatic flair to garden settings. The thick, deep roots of Chinese Rhubarb are notable, and the plant is hardy down to −20 °C (−4 °F).

Chinese Rhubarb is valued for its bold, architectural form and its striking foliage, which can create a focal point in a border or as part of a larger herbaceous planting. It is also used in traditional medicine for its purgative properties, although it should be noted that the leaves are toxic if ingested. This plant prefers full sun to part shade and requires well-drained soil with consistent moisture. While it is generally easy to maintain, it can be susceptible to crown rot if the soil is too wet. Propagation is typically done by seed in the spring or by root division in spring or autumn. Gardeners should be aware that while it is not typically invasive, it can form large clumps that may require division to manage size and vigor.CC BY-SA 4.0
