I tapped into the climate records from the University of Georgia cold duration calculator. So, it's not just my imagination, but this past winter has been a particularly prolonged cold winter. This winter our purple heart plant died, but this plant survived the past 5 winters outdoors.
Has prolonged cold temperatures altered when trees bloom or the arrival of other spring markers? My backyard record keeping could be better, but it looks like a ~19 day delay of spring markers when comparing 2010 with 2009.
