Cobblers pegs are considerd a nuisance weed here ( sticky seeds) and is native to Europe. We had a lot of rain during summer here and have an amazing crop of this weed. The Bees are bringing in ( so it seems to me) nectar and pollen and are working the plant most of the day. Has this plant escaped to other parst of the world? It is know for a lareg part of the coastal east coast of Australia.
