Rubia tinctorum

Rubia tinctorum, or Madder, is a herbaceous perennial vine primarily cultivated for its roots, which yield a natural red dye. It features sprawling stems that can grow several feet long, adorned with lance-shaped, rough-textured leaves arranged in whorls around the stem. Small, yellowish-green flowers appear in clusters during the summer. While it can be grown in gardens, it's not typically suited for indoor cultivation due to its vining habit and need for ample sunlight. People grow it mainly for dye production and historical interest.
