Hi Everyone

Hoping that some of the experts on the board can help me out here. I currently have a Prosthechea Elfin in bloom, and a Cattleya intermedia var coerulea which is due to open any day now. I was thinking about whether I might be able to cross the two? Would it work? I see some other Catt x Prosthechea crosses listed on the RHS site, but am unsure if this one would work. Can anybody advise? I have heard some info about the pollinia count in some Catt's but I am a newbie to this so any info provided would be greatly appreciated!!
