Nursery contributed plant descriptions

Woad! Grow this if you need to dye some cloth, or yourself for that matter, blue. Also not too bad in the garden. A biennial or short lived perennial, it produced a low mound of foliage the first year, then big masses of yellow mustard flowers up to three feet tall the next. Native to Europe, and classified as an invasive weed in much of the Western US, so probably best not grown out there. Zone 5
