Paul,
Nice. Is that Neoporteria nidus on the right?

Lincoln, NE USDA 5

If you mean the one sitting on the brick in the square green pot, I believe that is Neochilenia Napina.

Very nice collection, is that Echinopsis eyresii(sp),top left? I have a small Echi hybrid but no signs of buds yet.

Paul, Im intrigued by the unusual pot with the slits in,containing an Echinocereus?
What kind of pot is that?

Larry -- I don't know what the top left cactus is. I posted it in flower once before and someone identified it as a "Hollywood" cactus. The pot with the slits in it is just that -- a pot with slits. Mostly commonly used for orchids. I have a plastic liner inside the pot, which negates the effects of the slits. I believe the cactus inside it to be a Echinopsis Chamaecereus hybrid ("peanut cactus").

Very nice. Be sure to show us the flowers. I also have the plant on the lower left. Do you happen to know what it is?

Well, the top left one is definitely an Echinopsis of some sort, and I expect the flowers will be white or poink and posily fragrant!

I don't know what the plant on the lower left is. I'll post another pic when the bloom is open and maybe someone will be able to identify.
