I've been following the thread on these fascinating crosses with great interest. In my part of the world - the west of England - the main hardiness issue is not so much cold, as mild, wet, stop-start winters, when the ground never freezes. Not an ideal climate for succulents but some of the crosses that have been described sound as though they would be worth trying in these conditions. I have some seedlings of Manfreda virginica, courtesy of a generous fellow PBS member, but no Polianthes or intergeneric hybrids. Would anyone with access to seeds of the species or the hybrids have any interest in exchanging them? I have lots of fresh, wild collected hellebore seed to swap, as well as smaller quantities of some Balkan bulb seeds (spares of which I'll be sending to Dell to distribute through the BX). Anyone who might be able to help or who has experience of growing these plants in the sort of conditions I've described. can contact me via the forum or privately.
