Tall Blue Lettuce

I love this name. Small flowers, under a half inch wide, that are only open when it’s sunny. A thick cascade of flowers–can be blue, but these are white. A tall plant, up to 15 feet, with milky juice. Has a history of medical uses but not of food use. Annual or biennial. Aster family.
