About Common madder
Rubia tinctorum, commonly known as Madder, is a perennial herbaceous plant from the Rubiaceae family, renowned for its roots that yield red and orange dyes. It features square stems and lance-shaped leaves arranged in whorls, with small yellowish flowers blooming in summer. It's ideal for dye gardens, rustic borders, or even in large pots to harness its dyeing properties.

Care tips
It prefers full sun to partial shade and regular watering to keep the substrate slightly moist, but not waterlogged. Well-drained, fertile, and slightly alkaline soil is ideal for its growth. Avoid prolonged drought, especially during warmer months, as this can reduce pigment production in the roots.
