I understand wanting something that doesn't really grow in one's zone. But the usual outcome is that, instead of getting the gorgeous thing you're envisioning, you'll likely get a plant that suffers and has a forever lackluster look. Why not grow something that us people in crape myrtle country are forever pining about because we can't have it? I miss a lot of Yankee plants that just don't work out in Florida. If only I were in zone 6!!!
