This succulent has very tight leaves, that wrap around each other. There are very small spikes on the end of the leaves. I call it my brain succulent. I'd like to enter it in the fair, but I need a name. I bought this at either a home improvement store or maybe even a 99c store, and it has grown from a few centimeters to over 18cm (7 inches) wide. The photo shows an inch ruler. Any help with the name would be much appreciated. Thanks!
Crested Opuntia or Mammillaria I believe. If it has milky sap (Latex) then Euphorbia. http://www.cactus-art.biz/schede/EU...s_cristata/Euphorbia_pugniformis_cristata.htm
What a quick response. Thank you, Saltcedar! Yes, it has a milky sap and the link you gave shows a plant that looks like mine--so it's a Euphorbia pugniformis forma cristata. Upon further Googling, I've just found this photo and it looks identical to my plant: http://www.flickr.com/photos/sweetstuff1957/2755591935/
