About Rhubarb
Rhubarb (Rheum rhaponticum), also known as munkrabarber, is a perennial plant belonging to the Polygonaceae family, valued for its edible stalks and ornamental foliage. It develops lush, vigorous growth with large leaves and reddish or green petioles, forming an imposing clump. It is ideal for vegetable gardens, garden borders, or as a focal plant in edible landscapes, providing dramatic texture and significant visual interest.

Care tips
Rhubarb prefers full sun to light partial shade and deep, fertile, well-drained soil rich in organic matter. Keep the soil consistently moist, especially during dry periods, but avoid waterlogging as its roots are susceptible to rot. A common mistake is harvesting too early or pulling stalks instead of twisting and pulling them, which can damage the plant's crown.
