About this plant
Paeonia lactiflora 'Kansas' is a bold and beautiful peony variety known for its rich, deep magenta-red flowers. The blossoms are large and fully double, with numerous petals that form a dense, rounded shape. The deep pink color of the flowers becomes even more intense as they mature, creating a bright display in the garden. These fragrant blooms appear in late spring to early summer, offering a dramatic contrast against the plant's dark green foliage, which enhances the color of the flowers.
'Kansas' thrives in well-drained, fertile soil and full sun, where it can grow into a bushy, rounded mound. It is low-maintenance and relatively resistant to common peony pests and diseases, making it a reliable and hardy choice for gardeners. Once established, it requires minimal care and can tolerate drought conditions. The bold, fragrant flowers and robust growth habit make it an excellent choice for gardeners looking for a plant that offers both ornamental beauty and ease of care.

Design tip
The long summer show pairs well with plants that peak earlier, keeping one area interesting for months. Because it is easy about light, use it to carry a planting from a sunny end of the bed into the shadier side.
