I would guess that Zigadenus (which I think might be Toxicoscordion or something new now) would be one of the most northerly of bulbs, but I would also think that some of the very tiny species of Tofieldia would be the most northerly reaching bulbs in the world. That's just a guess though. How far north does Veratrum grow? (It grows from a rhizome and not a bulb, but does that count?) _______________________________________________ pbs mailing list pbs@lists.pacificbulbsociety.net http://lists.pacificbulbsociety.net/cgi-bin/…
