basilgirl, is it this plant?

I have a small pup you can have. Private mail me your address and I'll send it. I had given this one to a neighbor but she nearly killed it. The plant is now in a small pot, doing better but could use a forever home. I'll check around the mother plant and see if there are any more pups popping up.

For cactus, I like Bach's in north Tucson.

Home Depot and Lowes carries them, especially in spring. If you're in Phoenix you could also call AZ Cactus Sales down in Chandler. They're one of the more popular agaves so they should be very easy to find. Good luck on your hunt. We'd love some pics after you find/plant them. :) happy gardening!
