I have been trying to locate any Cat Tail Euphorbia in Arizona with no luck. We are looking for 15 gallon size, but I'd take anything at this point. Does anyone know where I can buy them?

Very nice 'young' green color and it took two frosts without being covered so it holds up here pretty well in the Phoenix area.
