Once established, it will flower for many years with minimum care. What's more, it's extremely hardy and can easily withstand Vermont's harsh winters. The latter produces many flowers on single, shrub-like plants.
Most gardeners seem to have better luck growing the herbaceous forms.
However, don't rule out tree peonies. When fully mature and in full bloom, they are spectacular. Peonies are usually planted in the fall although may be purchased in the spring as potted plants. They are easy to grow and should be planted in an area that receives at least six to eight hours of sun per day. When grown in shady areas, they will produce good foliage but few flowers.
