Thanks, Danita!
I'd had a dark-leaved ornamental grass on my want list for some time now, but either the price was always out of reach, or what I wanted was too dear to ship. This offer combined with Santa Rosa's low shipping fee made it possible to get a few ordered this year.
I chose to try Pennisetum Regal Princess, and also another plant that I'd been after...a short cultivar of Sneezeweed, Helenium autumnale Mariachi Sombrero.
