I planted a small 1-gallon plant in early April and it has rapidly blossomed into an outstanding specimen. Blue Eryngo is considered an aquatic but I didn't have a water-garden area so I planted it in an almost-constantly-moist clayey area (no standing water) and the results have been positive. The blue-grey-green color and the breadth of the flowers is impressive. Five months of the warm season is too short a trial to come to any long-term conclusions but, so far, this has been a highly rewarding addition to the garden. It is native from NC down to North Florida and west to MS.
