RHS publishes a Lily Register periodically which lists the names and information as submitted by registrants world-wide, on newly registered lily hybrids.  We have some of these publications saved and available to download directly from this site since the RHS site seems to change their location frequently, resulting in lost time while searching to re-locate them.
