I want to plant a druid garden
Why not plant a hawthorn/whitethorn (Crataegus) tree and then leave a small patch around the tree wild? Just let what grows there naturally begin to grow. Of course, once you’ve planted that tree, it must never be harmed in any way or touched according to the folklore. Country folk in Britain use the haws to make preserves and the tree itself, with its haws, will attract wildlife. You could even decorate the tree with ribbons as some trees in Britain and Ireland at sacred sites are, and come May, you’ll have your own May tree. How about that idea?
