If you're looking for Tephrocactus geometricus, lots of luck and let us know if you find this fine Opuntia tribe member. It's also known as T. alexanderii v. geometricus. Mesa Gardens has it on their seed list.

Here is a link that might be useful: Like You Never Seed It Before

Mesa Garden also sells the plant under the following record:
1250.279-alexanderi v geometricus DJF319 e Loro Huasi, Cat $8.00

One of the best places to get it is on eBay - user "teedeecacti" especially posts this species fairly frequently.

Although most on eBay are from Europe (which you can try via International shipping...I've never known such a shipment to NOT make it, but it *is* a risk), but set up a search on eBay to send you a message when one becomes available.

Good luck!

T,

That's odd - I did a search for the plant first and didn't find it, so thanks for correcting my misimpression that they didn't sell it.

Thank you both, I will see what I can find out and let you know. Dottie

I got in touch with Steven Brack at Mesa Garden and he said he had several but I did not see where I could order so I am waiting to hear back from him on how to order. I guess I am not smart enough to figure it out. Dottie

Dottie,
teedeecacti sure enough just listed this species:

Thank you Minime, I am going to give it a try. You are the greatest. I'll let you know what happens. Dottie
