Dear Ken, Of course the flowers have the last word on things. Yes some triploids can be fertile, others produce fertile pollen or ovaries. Anything can and does happen somewhere in the plant kingdom. I believe this is enough encouragement to continue to try to make "impossible crosses". We've all heard of people making the same cross hundreds of times until one took and produced a new race of hybrids. If roses and day lilies can do all these odd things, why not some other plants? Keep at it. Jim W. -- Dr. James W. Waddick 8871 NW Brostrom Rd. Kansas City Missouri 64152-2711 USA Ph. 816-746-1949 Zone 5 Record low -23F Summer 100F +
