Eric and all Hardy Hibiscus enthusiasts,
J Berry Nursery (800) 993-3352
is the wholesaler for the Summer Spice series from Texas A&M University. I left a message one day, got a call back the same day, and was able to find out which varieties, how many shipped, and ETA to my nearest Lowes that were on their list for the Summer Spice series. They only had ONE Lowes in MO, and 3 in Arkansas. They mentioned having locations in Texas, too, but I did not ask for details. They may not even be shipping to your state this season...
