Reseda Luteola

A lovely architectural plant with waving, almost snake-like heads, of small, tufted yellow-cream flowers, the appealing rosettes of yellowish green leaves acquiring a reddish blush in cool weather. This species was the most widely used source of the natural dye known as weld, a bright yellow dye. If mixed with the blue from woad, (Isatis tinctoria), it produces greens such as Lincoln green.
