Daphne, you might look at Magical Encounter (pink), Blue Suede Shoes (blue), Victoria Falls (lighter blue), Rosalie Figge (purple), which all rebloom in our zone 10a garden. Magnificent Masterpiece is a rebloomer - I planted it in France this year so don't yet know how it will perform. I added quite a lot of rebloomers over the summer - I'll let you know how they get on. One of them, Cotillion Gown, sent up a bloom stalk just a few weeks after it was planted (not pink, blue or purple, but very pretty):
We fly back to France on Tuesday, when I get to see how the new rhizomes have settled in.
