Perennial growing back each year in Spring from a stock of fleshy roots that lignify with age.

Fragile stems unable to support themselves, little or not branched, square section, with small hooked spines which cling to clothing, 1.5 to 2 m long. Uninterrupted growth from spring to fall. Upright habit when the plant finds a support in which to grow, lying down otherwise.

Leaves united by 4 (to 6) in whorls evenly spaced along the stems. They are soft green to bright green, slightly leathery, and like the stem, have small hooks allowing them to grip.

Flowers tiny, yellow star of 5 petals, united in not very dense racemes at the end of the stems. Blooms from early summer to early fall, followed by small - green then black - berries, each containing a large seed.

The root contains several tinctorial principles, including Alizarin which provides magnificent reds for Dyeing and Fine Arts.
Dyeing power is independent of the age of the plant, but the produced biomass increases year by year (according to ISBN 978-0-470-51199-2 pp. 43-44: "The dye content does not change during this
time, but the dry mass yield increases continually from year to year").
This is why harvest occurs after 2 or 3 years in cultivation - however harvest can take place on the year of sowing after 6 months of cultivation only.


Sow in March in deep pots so that the roots can develop well, in a mixture of loam and potting soil, warm and in the sun, under shelter from frost. Quick germination.

Young plants are often eaten by slugs, take all precautions.

For Multiannual Cultivation in open ground : End of May or beginning of June, when the plants are sufficiently developed, transplant in open ground at a sunny place, in a soil well loosened and enriched with manure compost. Water regularly the first year when necessary, while the plant takes hold. Weed regularly. Cut off dead parts in winter. Cultivate 2 to 3 years before harvest.

For Annual Cultivation in pots : Plant several plants in very large pots (wide and high), in a mixture of loam (1/3), potting soil (1/3) and manure compost (1/3). Place in full sun. Water regularly. During the summer, add liquid fertilizer regularly.

Harvesting Roots in October-November

Plants cultivated for several years in the ground : Extract the stump in the 3rd year, taking care not to lose any roots (they break easily and stay in the ground).

Plants grown in pots : Turn the pot over to drop the root ball.

Then, shake the soil from the roots to remove as much soil as possible, and wash the roots with clean water.
Sort them to remove dead or diseased roots.

Use immediately or Store (cut into small sections and dry at 25°C as quickly as possible. Store in this form in a dry, cool and dark place, or grind before storage).
