Do you have any growing near, considered picking it? I know you wouldn't get a whole lot that way, but enough to get it started. I picked a bunch last year but didn't plant it. Got a little nervous it might take over. But I've changed my mind. I'm going to plant some. If you don't have any around, the stuff near my home is budding out and I'd be glad to get you some seed. Of course, it may not be the strain you are wanting. But it seems to grow well and the goats love it!
