My favourite peony is definitely Paeonia ‘Paula Fay’. It is stunning! In fact the first time I saw it I was shocked by its beauty.
The colour is a deep rose and the flower is a semi-double bloom. The best thing about it is that I never need to stake it. The first year I had it I staked it up in anticipation of the peony flop but it never happened. Now I don’t bother. It stands just great on its own.
