Phil, I don't think this is Earl of Derby. Mark Hooten gave me an Earl of Derby at the Glock's gathering and it is a green and yellow. Look at the Veitch catalog and it will confirm the coloration. I'll try to get a photo up soon. I may have an extra that I can bring to the auction.
Marie - you're correct. It's a green and gold - but how does it differ from Fred Sanders?
Anyone want to hazard a guess as to what the croton in the pics is?
