About Chinese rhubarb
Rheum officinale, also known as Medicinal Rhubarb or Yao Yong Da Huang, is a perennial herbaceous plant from the Polygonaceae family, primarily valued for its large, ornamental lobed leaves and medicinal rhizomes. It grows to a considerable size, creating a strong visual impact in naturalistic gardens or as a focal plant in wide borders and beds. Its reddish stems and whitish to pinkish flower panicles add seasonal interest.
Native range
China and Tibet
Care tips
It requires full sun exposure or light partial shade in warm climates, and deep, fertile, well-drained soil rich in organic matter. Watering should be regular to keep the substrate consistently moist, especially during dry periods, but avoiding waterlogging. A common mistake is planting it in heavy or poorly drained soils, which can lead to root rot. Ensure ample space for its development, as it can grow quite large.
