Some years ago I was proud to have a division of a Paph I loved for its dark red pattern on a white background: Paphiopedilum White Shimmer 'Dazzle'. I tried to cross it with various Brachys but no one took and all failed. The only cross, that resulted in offspring is the one with Paphiopedilum coccineum. To my regret I lost P. White Shimmer because of an cultural mistake. So Paphiopedilum Andrea Mantegna is the only direct offspring I could get of P. White Shimmer.
