I've got fennel and yes it sefl-seeds but they're easy to spot and remove before they get too big and they look gorgeous in winter with the frost on. Do like the idea of the bulb version for swallow tails tho
I'm growing nettles too. No I haven't gone mad - they've got quite shallow roots which run so to counter that I'm planting a clump in a buried container as you would mint. They've been in a container that's no more than 10" deep since last August and they've made a lovely stand already so it's working.
I'm just desperate to get mor beutterflies in the garden so I'll try anything!
WIll go for the angelica sage and maybe the valerian this year
