Planted Peonies Yesterday

I planted some Peonies yesterday the temp. was at least around 50 degrees, but last night the temp. dropped down to around 20 degree's , and what I would like to know with the temp drop would it hurt my newly planted peonies?

Zone 5

You are fine, cold weather will not hurt your newly planted peonies. I've planted the after the ground was froze (dug hole earlier and kept fill dirt in gargage) and they thrived quite well. :)

Thanks, and what a relief
