herb garden planting Sept too late?
I am making my butterfly (full sun) garden and I decided I wanted to add a few 'herbs' in two raised beds in the garden. They won't really be for eating just looks and hopefully to smell. I want to put Lavender, Jerusalem sage, Lemon Thyme, Woolly Thyme, maybe a few Pink Delight Monarda(smells like roses so pretty!), and maybe some chives and mint(maybe). My problem is I live in zone 3/4 so our growing season is coming to an abrupt halt here pretty quick. Should I wait until next spring/summer to plant or do I have still enough time to plant the end of Aug/Sept.?
