Kansas peony basics

Kansas peonies are frilly red-pink peony flowers with double-petal blooms. The Kansas Peony was bred by Myron D. Bigger of Topeka, Kansas, and was introduced in 1940. The Kansas Peony received the 1957 Gold Medal from the American Peony Society. Myron Bigger became the president of the American Peony Society from 1958-1959.

Peony ‘Kansas’ has large double flowers, reaching 8″ across. These large blooms are supported by very strong upright stems. While the flowers do not have a floral or any delightful fragrance, they have the appearance of old-fashioned garden roses. The plant also showcase dark shiny lobed leaves in the form of foliage and exceptionally strong stems.

The flowers of ‘Kansas’ are termed “Doubles”, as they have multiple layers of petals. These big, fluffy, puffball-like flowers are among the largest types of peony blooms (and certainly the heaviest!). Other types of double peonies include Karl Rosenfeld peony, Sarah Bernhardt peony, and Festiva Maxima peony.

The Kansas peony grows to be between two and three feet tall with a similar width. It has green foliage and boasts a magnificent white flower that grows to be between six and seven inches wide.

This peony variety is set apart from other white peonies by the hot pink edges at the tip of the serrated petals. These peonies look as if the petals have just barely brushed up against red-pink dye.

What type of peony is the Kansas peony classified as?

Kansas peonies (Paeonia lactifloraKansas’) are herbaceous perennial plants with Full Double-type peony flowers that bloom early in peony season (typically early-mid spring).

Peonies come in six main types of flower forms: Single, Anemone, Japanese, Semi-Double, Bombe, and Full Double. Full Double peonies like ‘Kansas’ are known for their voluminous layers of petals. In this flower type, all stamens and carpels in the centre of the flower are transformed into petals. Double peonies look like a flower inside a flower (hence the term “double”).

There are three main types of peony plants: tree, herbaceous, and intersectional. Kansas Peonies are among the herbaceous category of peonies.

Kansas peonies in the garden

Growing Kansas peonies

Like most peony plants, Kansas requires only minimal maintenance as long as they’ve been planted in the right spot.

The Kansas peony only blooms in spring but is resilient throughout the year even into the winter. When the blooms start to die down at the beginning of summer, it’s time to start cutting them back. Remove spent flower heads and cut back the rest a little way into the foliage, preferably to a strong leaf, so that the stem doesn’t stick out.

Planting location

Plant peonies in hardiness zones 2-8. Their preferred garden zone is usually 4-7, but Kansas Peonies are a little more resistant to the heat than your average peony, meaning that it tends to thrive in the 8 climate zone a little better than most. This does not mean that it can be grown in hotter climate zones than this—8 is still the maximum.

Within your garden, this herbaceous peony grows best in a spot that gets plenty of bright sunshine and has deep soil with good drainage. If you find that the peonies begin to dry out, replant them in an area that receives light afternoon shade or partial shade. Like other peonies, it struggles to compete with trees, bushes, or shrubs, so be sure to plant it away from those.

When planting more than one of them, plant them three to four feet away from each other for the best results.

Soil for healthy peonies

Peonies like soil with a neutral to slightly acidic pH that is deep and drains well. If you have soil that is capable of growing plants without fertilizer, then there is no reason to use more than a tiny bit of fertilizer for these flowers.

Planting peonies

The best time to grow peonies is through early spring planting or later in the fall. The best time to move them is in early fall (although they don’t love being moved). It is important that the root system has at least six weeks to settle in before the ground freezes.

Most new plants are sold as bare roots. Plant peonies in a hole about a foot wide and a couple of feet deep.

It needs to have enough space for the plant to grow roots in. At this point, you’ll want to mix your compost with the dirt.

Next, you’ll build a mound in the hole that peaks no less than two inches from the surface. This is where you will rest the root itself, with its eyes facing towards the opening of the hole.

Now push the soil back into the hole, being careful to make sure that the bare root peonies don’t end up getting pushed further than two inches beneath the surface. cut flowers cut flowers foliage remains attractive

The peonies planted should be water generously and have the soil tamped gently to ensure that they have what they need to grow.

Caring for peonies

While peonies don’t need a lot of attention, it is a good idea to give them some kind of support for their stems. This can be wooden stakes, metal peony circles, or even tomato cages. Peonies don’t mind metal, so don’t worry about that bothering them.

There’s no need to mulch them heavily, even in the winter. If you do decide to mulch them, light mulching will be fine. Peonies are very cold-hardy!

Along with trimming back dying blossoms, you should also trim the peony plant’s foliage to the ground before each winter to protect it from overwintering.

Pests and diseases

Fortunately, Peonies in general aren’t vulnerable to many pests. Not only do they resist deer and rabbits, but they also have a symbiotic relationship with ants that protects them from things like slugs or aphids. They can, however, contract a variety of diseases if you aren’t careful with them.

Peonies are vulnerable to powdery mildew, which is rarely lethal but can make life much more difficult for them.

The best way to prevent this is to keep them in full sun and treat any signs of mildew right away. Full sun will not only help the plant grow healthily but also suppress any fungus growing on it. Good air circulation is also helpful.

Many infections that peonies can suffer from require you to either remove the affected part of the plant to remove the plant altogether. Never leave dead plant foliage, stems, or roots in your garden!
