These were difficult to grow. Had to stratify and so far only 4 plants are growing. All still very small, under a foot high. Hope they come back next year!

After putting seeds on a moistened paper towel in a baggie in fridge had good germination. I even had monarchs laying eggs on the leaves after transplanting the seedlings into the ground.
