Looking for seeds or plants of Astrophytum asterias, otherwise known as sand dollar cactus. All I have to offer at the moment is basil seeds and a mix of sunflower seeds (pictures here: http://www.flickr.com/photos/satinandlace08/sets/72157624589350490/). I am also currently growing some Kalanchoe daigremontiana, mother of thousands, but the babys aren't big enough yet.
