RAH, I had bookmarked Mike Giles' Turtle Island Waterlilies last fall for the same blue hardy lilies, and they've cancelled online sales. I was waiting for spring to hit before I ordered their blue lilies, but it seems all the sales are wholesale now, and they require a $500 minimum order. I also contacted Dr. Brent Pemberton from Texas A&M AgriLife Research and Extension Center, and he referenced Turtle Island as the only store that he knew had the blue hardy lilies.

If I do find them, I'll let you know.
