Peonies have long been a favorite for their easy-growing nature, making them a welcome addition to almost any landscape. These low-maintenance plants thrive for decades, needing only minimal care from growers.
The most vibrant peony varieties deliver the biggest visual impact, offering gardeners reliable seasonal displays. Take ‘Kansas’ peonies, for example—they produce an abundance of gorgeous double-pink blooms.
‘Kansas’ peonies also have a light yet romantic fragrance. They bloom from late May to early June and make excellent cut flowers. Their dark pink, frilly petals add charm to bouquets or shine on their own. Plus, their delicate scent creates a lovely atmosphere in any room where they’re displayed.
Caring for Kansas Peony
Let’s dive deeper into how to grow ‘Kansas’ peonies, focusing on their specific needs and ongoing care.
Light
For the best results, plant ‘Kansas’ peonies in full sun. Established plants do best with at least 6-8 hours of direct sunlight daily. While they can grow in partial shade, plenty of sun ensures the best bud production.

Temperature & Humidity
Peonies thrive in cool conditions. Mild spring temperatures (60-70°F / 15-21°C) help both flowers and foliage grow strong. While they can handle warmer weather, high heat and summer humidity may stress them. On the flip side, peonies are impressively cold-tolerant in winter, needing a seasonal chill during dormancy.
Water
Though established plants can handle some drought, consistent moisture supports steady growth. Water peonies regularly in summer, about 1 inch (2.5 cm) per week. Deep, bottom-up watering helps maintain proper soil moisture.

Fertilizer
While not mandatory, fertilizing peonies can boost growth and blooms. Experts recommend a balanced, slow-release fertilizer applied in spring and fall. Early feeding (just before new growth appears) gives plants a strong summer start. Late feeding (after cutting back in fall) supports root development.
Soil & Compost
Peonies adapt well to different soils, as long as drainage is good. They thrive across various pH and fertility levels, but adding compost at planting helps new beds establish better. Soil tests can fine-tune nutrient and soil structure management.
Where to Grow a Kansas Double Peony
‘Kansas’ peonies love full sun, making them great for mixed beds, borders, or foundation plantings. Like many large varieties, they can also be planted in rows to form small hedges.
Avoid planting them near large trees or structures that cast shade. If space is tight, grow them in containers—just choose pots big enough for root growth.
How to Plant a Kansas Peony
The ‘Kansas’ red peony is popular, so bare roots are usually available at garden centers. While spring planting works, fall planting is often preferred—it gives roots time to establish before the first growing season.
For first-time planters, dig a hole twice as wide and deep as the root. Place each growth eye no more than 2 inches (5 cm) below the soil surface. Water well after planting to settle the soil and encourage growth.
Pruning
Pruning is key for peony care. Remove faded blooms to prevent seed production, redirecting energy to plant health. In fall, after the first frost, trim back browning foliage to prep for winter and reduce disease risk.
Problems, Pests & Diseases
Peonies rarely struggle with foliage issues, but some diseases can occur. Fungal infections like powdery mildew, botrytis blight, and leaf blotch (or “peony measles”) are the most common. Early detection and prevention are crucial.
Pests like aphids, mites, and mealybugs may bother peonies. While ants often crawl on buds and leaves, they’re harmless.
Propagation
Peonies are usually propagated by division while dormant. Carefully lift roots, cut them into sections (each with multiple “eyes”), and replant, store, or pot them.
Growing peonies from seed is possible but slow, and the results won’t match the parent plants.
Are Kansas peonies better in pots or the ground?
While many gardeners prefer planting peonies directly in beds, ‘Kansas’ peonies can grow in pots. Just choose a large container with good drainage and use high-quality potting soil for best results.
