About Chinese rhubarb
Rheum palmatum, commonly known as ornamental rhubarb or Chinese rhubarb, is a majestic perennial plant from the Polygonaceae family, valued for its spectacular foliage. Its large, palmate leaves, often with reddish or purplish hues, can reach up to 1 meter wide, creating a dramatic visual impact in moist gardens or by ponds. It produces tall pink or white flower spikes in summer, making it an excellent focal point in perennial borders or naturalistic garden settings.

Care tips
It prefers a location in full sun to partial shade, with consistently moist, organically rich, and well-drained soil. Ensure copious watering, especially during dry periods, as it does not tolerate drought; mulch helps retain moisture. A common mistake is planting it in poor or dry soils, which will limit its growth and leaf size. Protect young plants from late frosts to prevent damage to emerging shoots.
