I have a theory that the over-tidy, clear it up, spray it, kill it, attitude of many gardeners destroys a lot of the easier to kill life in the garden leaving it at the mercy of the real bullies. Left to itself it all balances out and nothing reigns supreme.
There is HF here, 2 old willows died of it and possibly a clematis and a ceanothus (inconclusive).
Everything else just goes along, tree paeonies, lots of shrubs and trees. Native trees have probably learned to live with it
