Yucca glauca is dependably hardy in St. Paul, MN and some distance
further north. Yucca filamentosa will winter here only in protected
locations. In climate as cold as ours yuccas lose most of their
previous years foliage and resprout from the stock near the ground;
thus it is temperature near the ground under a layer of snow that
matters. I doubt that the temperature at such a point ever gets below
-15 C around here, whereas the air temperature can dip to -35 C. I
expect that wintering Yuccas is easier if planted in a very sharply
drained soil since root rot contributes to most loses.
Seed germination is easy without pretreatment at 20 dregrees C.
Presoaking might help.
