Mid winter Yellow Fever

I was covering tender mini’s with styrafoam before our cold snap (8F, -13C here in WV) since it was coming with no snow cover.  Found just a pot of Yellow Fever with bud stalks too mature to make it through the cold (not to mention being pressed down by styrafoam and rocks.)  Pulled the pot and brought it inside and the first bud opened yesterday.  Last year it had a sensible mid-march bloom date, even after a very mild winter and early spring.  No idea why it’s so early this year, but it certainly is welcome.  The bulbs were a gift from Beverly Barbour so I’m relieved to have proof I didn’t kill them!  Pretty little thing.
