Being very new to mediterranean gardening, I am constantly having to revise my ideas.
In my naivety, I assumed that annuals that flower all summer long in the U.K., would do the same here if given water at regular intervals.
So I sowed some Cosmos bipinnatus Purity along the top of a dividing wall, to separate two areas in my little garden.
This worked well for a couple of months.

However, I couldn't keep up with the deadheading.
They gradually became less and less attractive, going to seed and producing a lot of die back.
This morning I have pulled them all out.
Is there an annual that would keep flowering and looking good all the way through the summer?
I have some narcissus in the top of the wall, so an annual would work best there. I can just sow over the bulbs.
It would have to be in white, or, possibly blue would work as well.
I have tried to think, but all I can think of, is Euphorbia marginata. That would be fine, except the ones in my neighbourhood, have only recently started flowering. I would prefer something that would flower all summer.
Umbrian's forking larkspur looks lovely, but would it flower all summer?
