Peony ‘Kirinmaru’ (Paeonia lactiflora ‘Kirinmaru’) is a distinctive herbaceous peony known for its unique flower form and elegant colouring. The blooms are typically large and fully double, opening in late spring to early summer. Petals are often soft pink to blush with a refined, layered appearance that gives the flower a full, rounded shape. Strong upright stems support the heavy blooms above lush, deep green, divided foliage. This variety adds classic beauty to perennial borders and makes an excellent cut flower.
