Leadfarmer - looks lovely. I add globemaster alliums to my purple sensations - they flower just slightly later ( but overlap with PS) so the show gets extended by 2-3 weeks. They are a bit more expensive, but you don't need many of them.
Thanks, Berghill, for the aster reference - its gone in my little black book (except its pink!)
