You can see a picture of the parent plant and an explanation in the Cacti Gallery.

I can send an up-to-one-pound box (with a Fang leaf and other cuttings,* pups, or newly-rooted succulents from my garden) by Priority Mail ($4.05 anywhere within the U.S.), or we can trade. I do not want cacti that grow big, but any other succulents would be fine, and right now I would be especially happy to get gasterias.

*Will throw in a Synadenium compacta rubrum cutting for the first two people who respond (and want one, of course). I can send you a picture of the parent plant if you let me know your e-mail address.
