Thank you, Angelo. Interesting. I want to try the cross Hymenocallis occidentalis --hardy down to -5 ° F ( ~ minus 20.56° C) I do not necessarily expect an easy cross or even that this can occur. My reasoning is that H. occidentalis might have separated much earlier from the rest of the Hymenocallis and therefore might have preserved some features that would enable it to cross with other related similarly structured relatives. The chriomosome nos. seem not to favor the idea, but are in the realm of possibility , not unlike lycoris, with the haploid number allowing for some slippage Of course the opposite is equally likely. The occidentalis could be more cold hardy because it is more evolved and furher away from its origin, just as maritimum is further away from its common origin with either Hymenocallis or Ismene. This is not ordinarily even worth considering. But I'd like to try it. Sort of like super wide orchid crosses. Besides it might be interesting to try to grow P. maritimum. ----- Original Message ----- From: <ang.por@alice.it> To: <pbs@lists.ibiblio.org> Sent: Tuesday, March 09, 2010 2:20 AM Subject: Re: [pbs] Pancratium maritimum - hybrids 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/…> -------------------------------------------------------------------------------- > _______________________________________________ > pbs mailing list > pbs@lists.ibiblio.org > http://pacificbulbsociety.org/list.php > http://pacificbulbsociety.org/pbswiki/
