I have ordered many peonies from Wild. Most of the time I got what I ordered.
They do refund when they make a mistake, but you have wasted a year.
My worst experience was with Park Seed. Several years ago I ordered Itoh 'First Arrival.' It was a tissue culture plant and took 2 or 3 years to bloom. They replaced it with another tissue culture plant that took 3 years to bloom. It too was not true to name. They refunded my purchase (not shipping), but I still do not have the plant I wanted.
You do not normally get tissue plants from Wild and the plants usually bloom the following year. But the real plus for Wild is price.
