I have several Opuntia diademanta (they have 2-3 inch long spines that are soft and flexible as thick paper - not at all painful, but look fearsome). I also have some Rhipsalis pilocarpa,Agave americana glauca (blue) pups, as well as a number of Lithops (aucamiae & salicola) & Haorthias (cymbiformis & pumila).

I am looking for Sedum (aka Rhodiola) rosea & Agaves: amer. 'variegata' with gold margins, A. parryi, A. stricta;

Orthophytum 'Copper Penny' & any sempervivums, but especially S. 'Borisii'.

Check out my trade lists - they're extensive. Tempt me!
