About Rhubarb
Rhubarb (Rheum rhabarbarum) is a herbaceous perennial plant renowned for its edible stalks, which range in color from pale green to deep red. Its large leaves with thick petioles emerge from an underground crown, creating striking foliage. It's ideal for vegetable gardens or as an ornamental plant in garden borders, adding texture and a rustic touch.
Native range
Central Asia and Siberia
Care tips
Rhubarb thrives in full sun to partial shade, in rich, well-draining, slightly acidic soil. It requires regular watering, especially during dry spells, to keep the soil moist but not waterlogged. A common mistake is harvesting stalks in the first year after planting; it's best to wait until the second or third year to allow the plant to establish itself. The leaves should never be consumed, as they are toxic.
