I was kind of lazy last Fall and didn't harvest seeds from two of my
vines, Hyacinth Bean and Moonflowers. Now we're having a sub zero cold
front and I'm wondering what's going to happen to these seeds. The
morning glory seeds always seem to survive winters here but I haven't
ever let the Moonflower or Hyacinth Bean seeds overwinter outside like
this. Does anyone know if these seeds will survive or will I have to
buy them again next Spring?
