1. Aquilegia (Columbine)
2. Not sure, maybe a young Ceanothus?
3. Smokebush (Cotinus coggygria) purple leaved cultivar
4. Tossing up between Kolkwitzia (which we're now supposed to call something else I've forgotten) and Weigela. Leaning towards Weigela, or maybe Abelia. Tried to enlarge photo for a better look and page crashed and reloaded so I lost what I'd already written and had to start over
Someone else will help with that one.
