Peony Kansas

Peony 'Kansas' is a striking herbaceous variety prized for its large, fully double, rich magenta-red flowers. The densely packed petals create a bold, ruffled display that stands out in any garden. Flowering in late spring to early summer, this vigorous peony has strong stems that support its vibrant flowers, making it an excellent choice for cut arrangements. The deep green foliage provides lasting interest throughout the growing season, adding texture and contrast to borders and garden beds.

Perfect for garden beds, borders, and cut flower gardens. Adds dramatic colour and structure to perennial plantings.

Thrives in full sun to partial shade in fertile, well-draining soil. Space plants approximately 60 cm apart for optimal growth and airflow.

Grows to around 80–90 cm tall and 60–80 cm wide.

Trimming: Cut back foliage to ground level in late autumn once it has died back to encourage strong regrowth in spring.

Deadheading: Remove spent flowers promptly to maintain a tidy appearance and redirect energy into root development rather than seed production.

Fertilising: Apply a balanced fertiliser in early spring as new growth emerges. After flowering, use a low-nitrogen fertiliser to support root health and next season’s flowering. Avoid excessive feeding, as this can reduce flower production.

Watering: Keep soil consistently moist during the growing season, especially in dry periods. Deep, infrequent watering is best to encourage strong root development.

Pest Control: Watch for aphids on young shoots and treat with insecticidal soap or a strong jet of water if necessary.

Disease Management: Peonies can be prone to botrytis blight, which causes blackened stems and bud rot. Remove affected growth immediately and ensure good air circulation. Avoid overhead watering to reduce fungal risks. A copper-based fungicide may help if problems persist.
