Mystery plants are aquilegias. The laves are a bit mildewed. Shear them off, water and feed for new fresh growth.
I leave lavender heads on over winter as the goldfinches pick the seeds out of them, but when the last florets are done, you can tidy the plant up by giving it a gentle chop back. Don't cut into old wood or it won't resprout.
Hydrangeas gently fade. If you don't like it cut it off. You could leave it over winter.
Stuff in pots needs more water than you think in summer.
