Good luck... my husband planted some globe thistle a few years ago and I have to dig it out every spring. It seems like if there is one tiny piece of root left, it can sprout from it.

Mine were blue, but I agree, they look like thistles. I dug some out and gave them to my aunt and she planted them under her bird feeder. She says the finches love them, so they have to be good for something.

Wendy, my feelings exactly. I found when I started WSing, I grew the 'safe' standbys, but as I am progressing, I find I want to try different things. For example, this spring I am digging up evening primrose and Ajuga to plant more interesting things. I am between two minds since reading your comment on 'Sea Holly'. I have been waiting two years for mine to flower and expecting it to be wonderful. I hope I don't have to dig it out. You will love Verbascum - I grew it a couple of years, but the neighbourhood cats would always dig them up each winter. I am now re-planting that bed so maybe I'll replace a spot for them.
