Can anyone help to identify these plants?
The top one looks like some sort of Broom to me :-/ I'm assuming its spiny and viscious?
Might be Potentilla fruticosa at the top
Choisya 'Aztec Pearl' or similar cultivar at the bottom
Second one I would say.... maybe Rosaceae - Prinsepia uniflora Batalin ?
Karoo plant maybe the top one?
Nutcutlet, just checked on RHS plant finder and I think you've got both absolutely right. Thanks a lot.
