Wild gardens take a lot of work to keep under control
I grow: Lavender; rosemary and other herbs; love in a mist; evening primrose which spreads, one can watch the flower petals unfurl in the evenings and moths/hover flies love them; poppies; borage which spreads gently; hollyhocks and foxgloves which seed, take 8-12 months to develop so open the following year.
Broad beans and sweet peas can be set in the Autumn, be aware of mice though
.
MayB draw a map of your garden and if there is room, make a wild life pond to encourage insects and dragon flies.
