About Dyer's alkanet
Alkanna tinctoria, commonly known as alkanet or dyer's bugloss, is a small perennial herb from the Boraginaceae family, prized for its deep red roots traditionally used as a natural dye. It features lanceolate, hairy leaves and produces small blue or purple flowers. This plant is an excellent choice for rock gardens, sunny borders, or as a low-maintenance ornamental in Mediterranean climates.

Care tips
It thrives in full sun exposure and well-drained soils, even poor or sandy ones; waterlogging is its main enemy. Watering should be moderate, allowing the substrate to dry out completely between waterings, and it is quite drought-tolerant once established. Avoid over-fertilization, as it can reduce the intensity of the color in its dyeing roots. A common mistake is planting it in heavy or clay soils that retain too much moisture.
