Plants that remind us of Guernsey

Afternoon all. The mrs and I are thinking of planting up things which remind us of Guernsey (we tend to go twice a year - until this this dreaded virus hit), but we are at a loss what actually to put in. Anyone got any suggestions - she seems to think a lot of white flowers but it's vague. I can only think off the top of my head of the obvious - Mexican fleabane and cordyline cabbage palm!

We're in Plymouth so climate isn't really a problem (and the obvious two I mentioned are everywhere here as well - which is no bad thing).
