This big plant is best in groups, it's an excellent cut flower, and the (bumble)bees love it.
I will trade for things that are on my want list, special alpine/rock seeds or anything special you have to offer. Something that's common to you, might be special for me. I live in Europe and I'm interested in wild plants who are not common in western Europe.
Annuals as well as perennials (hardy to zone 6) are welcome.
