It’s almost time for our beloved peonies by Vicky Spelman

Peonies are staples in our landscapes and have been grown, admired and cultivated for more than 1500 years.

There are three types of peonies and are generally classified by growth habit:  herbaceous, tree and intersectional with herbaceous being the most common.  The foliage of herbaceous peonies dies to the ground each fall.  

Herbaceous peonies typically grow three to four feet tall and have a round shape with dark green foliage.  The flowers are large, very fragrant, and often start blooming in May or early June along the Front Range.  

They do best in full sun but will tolerate light shade.  Peonies prefer rich, loamy, well-drained soil but can tolerate and bloom in a wide range of soil types.  They will live for many years in the landscape, so for optimal flowering place in a permanent location.

Early fall is the best time to divide peonies.  Planting later may not allow enough time for the plants to become established before winter.

Many peonies, especially the double-flowered varieties, need to be staked or supported to prevent them from flopping over when they are in bloom. A good way to support the plants is to place metal hoops or rings over the plants in early spring.

Water peonies when the weather is dry – this is important during bud formation and flowering – soak the soil to a depth of around 10-12 inches.  Buds may fail to enlarge and open if the plants are dry. 

What about ants on my peonies.  Ants are attracted to the nectar on the flower buds. They are not necessary for the flowers to open nor are they an indication of a problem.  

I just checked my peonies - sprouts are already starting!  Exciting!!!

That’s it!  Enjoy your peonies!
