Complete Plant Information
Overview
Paeonia ‘Prairie Moon’ is a highly valued herbaceous perennial peony, celebrated for its early-season performance and distinctive coloration. This cultivar produces semi-double, soft pale yellow flowers accented by bright yellow centers, creating a delicate yet eye-catching display in the late spring garden. As a robust Peony, it offers reliable yearly structure, dying back to the ground only after the first hard frost.

How to Grow
Planting Paeonia ‘Prairie Moon’ is best done in rich, fertile, medium-moisture soil that is well-drained. Incorporating ample compost before planting helps establish the necessary soil structure these peonies prefer. Ensure the planting depth is correct, as planting too deep or too shallow is a common reason peonies fail to flower.
Established Peony plants require medium watering, especially during dry spells, but must never sit in soggy ground. Maintenance is generally considered medium; remove spent flowers immediately after blooming concludes to clean up the plant’s appearance. Paeonia ‘Prairie Moon’ is known for being long-lived and generally does not require division for many years.
A critical late-season task is to cut the foliage of your Peony to the ground after the first hard frost in the fall and remove the debris from the garden area. This sanitation practice helps prevent overwintering fungal diseases. Support may be necessary for Paeonia ‘Prairie Moon’ as its blooms can be heavy and prone to arching, especially after rain.
Landscape Uses
Peonies, including the desirable Paeonia ‘Prairie Moon’, function beautifully as standards in the perennial border. They work exceptionally well when planted in groups or used singularly as focal specimens where their early season performance can be showcased against emerging summer growth. Their substantial foliage provides attractive structure even when not in bloom.
Consider using these robust plants as herbaceous hedges lining sidewalks or driveways. They look fantastic framing walls or fences, offering height and texture. Due to the showy nature of their individual flowers, they look best planted where they can be appreciated up close, either in foundation plantings or near seating areas.

Potential Problems
Peonies are generally considered quite pest-free, though vigilance against fungal issues like Botrytis blight and Phytopthora blight is wise, particularly in humid conditions. Ants are frequently observed gathering on the emerging buds; these are entirely harmless and should be tolerated as they help keep predatory pests away.
If your Paeonia ‘Prairie Moon’ fails to produce blooms, check planting depth first—depth is crucial for successful flowering. Too much shade or disturbing plants recently after transplanting can also inhibit bloom development in the current season. Since this cultivar produces large blooms, staking or using peony rings early in spring is highly recommended to prevent the stems from arching or lodging due to the weight of the flowers or heavy rain.

Companion Planting
When planning the border around Paeonia ‘Prairie Moon’, select companions that appreciate similar soil and moisture but bloom later to extend visual interest. Consider pairing them with early summer bloomers like Siberian Iris (Iris sibirica) or Oriental Poppies (Papaver orientale), as the Peony foliage remains attractive after its May bloom has finished. Avoid planting shallow-rooted, aggressive spreaders, as peonies dislike being disturbed or competing heavily for nutrients.
Seasonal Care Calendar
Spring preparation is vital for this Peony. As new growth emerges in early spring, gently clear away any old dormant foliage remaining on the ground. This is the ideal time to apply a balanced, slow-release fertilizer around the drip line, avoiding direct contact with the crown. Summer care focuses primarily on water needs, ensuring medium moisture, and installing peony support rings before the plants become too tall, which prevents the heavy blooms of Paeonia ‘Prairie Moon’ from collapsing.
