Has anyone used Sapphire? None of the farms or brokers that I have called know much about it, and none have had it available. Even if they are listed as a grower. It seems almost as elusive as Captiva. The marketing material states that it is one of the most aggressive St. Augustine strains out there, and supposed to do great in the shade. Post up if you have used it, or even if you know where to get it.
