Peonies are an investment once they start blooming they will bloom for years. Even without any sort of special care. These ones were planted as late as the 40's or 50's. They grow better if they are divided every 4 years or so ideally.
I like this photo too as you can see the Tiger Lilies in the back ground ready to go. I love the Tiger Lilies because once the Peonies' spectacular show are done the Tiger Lily is there faithfully ever year just like the Peonies. They put on an equally fantastic show and are a welcoming sight.
