Herbaceous clump-forming biennial or short lived perennial with conical spikes of small, green-yellow flowers which provide an excellent source of nectar for bees and butterflies. A yellow colorfast dye can be extracted from the leaves, flowers, and seedpods. It gets its genus name, "Reseda" from the Latin word "to calm," because the plant was said to have sedative properties, however this is not backed up by scientific evidence. Requires full sun and well-drained soil. Height to approx 60cm, space 30cm apart. Blends well with grasses and other grassland vegetation.
