Dyer's woad
Isatis tinctoria
Dyer's woad is a historic dye plant with bright yellow flowers that attract pollinators, best grown in a sunny to partly shaded spot with average, well-drained soil. Water regularly during the growing season and deadhead spent flowers promptly, as it can self-seed prolifically. Note that this plant is considered invasive in parts of North America, so check local regulations before planting.
