Crinum breeding: which features ?

Dear all,

I have to agree with Jim Waddick -- where he and I live (near the 40th 
parallel) hardiness is the overriding concern in Crinum breeding.  I have 
'Emma Jones' in the ground in a very protected site; is she fertile with 
anything else?

I found that the [bulbispermum 'Roseum' X lugardiae] hardy seedlings did 
not have any of the roseum color, but the flowers stood up reasonably 
well.  Next I'll try a backcross with a better bulbispermum parent.  Some 
of the [bulbispermum 'Roseum' X lugardiae] seedlings, planted out in the 
field, sent up three scapes in succession.  Rain is a problem, but Japanese 
beetles are a far worse problem where defacing otherwise pretty flowers is 

To get bloom all summer, I would have to have bulbispermum, macowanii 
(might be hardy here?),  then [bulbispermum 'Roseum' X lugardiae]  and 
finally variabile in my plantings.

And this is before we even think about flower form, color, etc.
