Ooh, I do love the color on the 'Citrus Cooler' Lin! I've been wondering if this is a named variety. It sure does look like Sorbet 'Tropical Peach'.
I first saw these in huge clumps at Selby Gardens, then was lucky to pick up a couple of pretty sad looking little plants on a trip to a wholesaler in Apopka, but no name tag either place. Those older plants are pretty big and healthy now, so they seem to do fine in my conditions, and even compete with my crazy all-engulfing oak tree roots.
I have white and yellow and two shades of purple as well as these, but the peachy ones are the most vigorous.
