The peony is one of America's best-loved perennials. Luckily, it is also one of the easiest to grow. These robust, shrub-like plants bloom for generations with virtually no attention. They tolerate a wide range of growing conditions, are rarely bothered by deer or other pests, and look attractive from spring through fall.
Of course the best thing about these hardy, trouble-free perennials is their amazing flowers -- blousy blooms as big as your hand and petals like brushed silk. With their soft texture and romantic colors, it's no surprise they are such a popular choice for bridal bouquets.
The only complaint one could ever have is that their gorgeous flowers come and go so quickly. Wouldn't it be great if you could have peonies in bloom for six weeks rather than two weeks? Well you can, and here’s how.
There are actually three types of peonies: tree, herbaceous and intersectional. Each type flowers at a slightly different time, and within each type there are early, mid and late bloomers. To extend the season, all you need to do is choose your plants based on their bloom time as well as on their appearance!
Tree Peonies
These plants have woody stems like a shrub and in moderate climates they can grow to 5 feet tall. They are the first peonies to bloom each spring and start opening at about the same time as late season tulips. The flowers are extra large (up to 10” across) and they come in a wide range of colors, including cream, yellow, gold, coral, lavender, pink and deep red. Shown above is Paeonia suffruiticosa 'Renkaku'.
Herbaceous Peonies
These are the old-fashioned “bush” peonies that die back to the ground every winter. Plant heights range from 24 to 36” tall, and flowers styles are classified as single, semi-double, double, anemone and bomb (shown above). They start blooming in early summer at approximately the same time as lilacs and continue for several weeks.
Intersectional Peonies
These hybrids (also called Itohs) are created by crossing an herbaceous peony with a tree peony. Itohs die back to the ground like herbaceous peonies. This makes them more winter hardy than tree peonies, but their flowers are as just as large and come in a similar range of colors. The foliage of an Itoh is similar to a tree peony and the flower stems are very strong. The variety shown above is Bartzella.
