I don't have this plant... It is a registered hybrid, Paph Éclair Blanc. But from what I know about Paphs, you may have a fairly long wait. Paph Lady Isabel (rothschildianum x stonei) is a multi-floral, section Coryopedilum (and they tend to be slowwwww) and Paph niveum is from section Brachypetalum, hybrids from dissimilar sections tend to be shy bloomers. So this may take awhile.
