Hi Pat, I'm sure you know that all with the Suburban prefix were hybridized by Earl Watts in Hattiesburg, MS. Their garden will be on tour at this year's National. When I visited there a few years ago for a Region 14 meeting, there were a lot of Earls plants growing in their garden, the Chain garden, and we visited Carey Robert's garden on that tour. ( around 2012 or 2013.). Sadly, Carey Roberts passed a couple years after that. You might ask a couple of your NVDS friends who will be at the convention to be on the lookout for it. Some of Earls plants might not be well distributed outside of Region 14. The two of his I grow do fine here, but they are Deep South plants.
