To Jim Shields and those interested, I have tried many times to cross Pancratium maritimum with Hymenocallis 'Tropical Giant' both ways without success, no sure about the fertility of that Hymenocallis but I know it sets seeds crossed with other species. But more interesting, I have also tried to cross P. maritimum and P. illyricum both ways and never got any seed, nor a pod swelling and the fertility of both species isn't an issue. best regards Angelo Porcelli Apulia - South of Italy Alice Messenger ;-) chatti anche con gli amici di Windows Live Messenger e tutti i telefonini TIM! <http://maileservizi.alice.it/alice_messenger/…>
