Dyer's woodruff
Asperula tinctoria
Dyer's woodruff is a delicate, shade-tolerant perennial prized historically for its yellow dye and small white flowers, growing best in humus-rich, well-drained soil in part to full shade. Keep the soil consistently moist, particularly during dry spells, and mulch around the base to retain moisture and regulate soil temperature. It is a specialist plant best suited to woodland or cottage garden settings and may require sourcing from a specialist nursery.
