" If I could grow L. vernum effectively, I'd be campaigning for a bulb of 
this interesting plant. However, both L. vernum and L. aestivum fail to 
flourish here and rarely bloom, probably because the soil (acidic, 
fast-drying) is wrong for them. In contrast, L. autumnale and the 
purportedly tender L. nicaeense do well in the open rock garden, though I 
don't depend on their surviving there indefinitely, once they encounter 
winter temperatures more severe than average. The larger species, which 
come from wet meadows, grow well at lower elevations near my home, where 
the soil tends to be dense and silty rather than the rocky subalpine forest 
stuff I have here; this suggests to me that it's the drainage, not the 
acidity, that is inhospitable to these plants."

I think you are right on all counts.  L. vernum fades away here in the spots
that get too dry too regularly but does fine in the spots that stay moister,
naturally or artificially.  All sites are acid.

Another Leucojum that has surprised me outside is L. tingitanum.  This has
been in the sandy bed in front of the house for the past three years, though
I don't remember putting it there.  It has flowered better as time has gone
by and even though that is the most sheltered spot in the garden it has
still seen temps between 5 and 10F, and been covered in deep snow many
times.  That spot also gets morning sun so the leaves will get lots of
freeze/thaw cycles.  It is in the same spot as Ipheions Alberto Castillo,
Rolf Fiedler and Charlotte Bishop.
