Their fragrance was as delicate and beautiful at their blossoms.
A quick internet search turned up some interesting peony quotes.
Some of my favorites were:
as pretty as a peony;
a peony for your thoughts (probably a play on a penny for your thoughts;
and when in doubt add peonies and a rose is a rose, but a peony is a friend forever.
While some spring flowers have faded, many more are ready to open.
This appeared to be the time for the peonies to show off.
That's just the nature of things round here.
