I'm surprised V.thapsis hasn't been an issue for me since it produces so many tiny seeds, but I typically just see 4 or 5 show up each year. Its funny how many comments that wildling gets from friends viewing the garden. I started a couple more species this year- I'm loving those plants that can take heat and dry conditions!
I had considered creating a forum for biennials...hmmm...perhaps it would be a good idea
