About Woad
Isatis tinctoria, commonly known as Woad, is a biennial herbaceous plant belonging to the Brassicaceae family, historically renowned as a source of blue dye. Its basal rosettes feature distinctive blue-green leaves, and in its second year, it produces tall flowering stalks adorned with small, bright yellow flowers. It is ideal for dye gardens, rustic borders, or as a low-maintenance ornamental plant.
Native range
Southeast Europe to Central Asia
Care tips
Woad prefers full sun to partial shade and well-drained soil, tolerating a wide range of pH levels. Watering should be moderate, allowing the soil to dry out slightly between waterings; it is quite drought-tolerant once established. Avoid waterlogging, as this can lead to root rot, and excessive fertilization is not necessary. A common mistake is planting it in heavy, poorly-draining soils.
