Plant Paeonia latifolia 'Madame Emile Debatene' where you can enjoy its classic peony form and late-spring flower show year after year. This herbaceous peony dies back in winter and returns strongly in spring with sturdy stems and fresh green foliage, making it an easy anchor for mixed perennial borders and cutting gardens.
Give your peony full sun for best flowering, with good air circulation to help keep foliage looking clean through the season. Choose deep, fertile, well-drained soil and amend with organic matter if needed. Water regularly during active spring growth and bud formation, then taper to occasional deep watering once established. Avoid soggy sites, which can stress the crown and roots.
When planting, set the crown so buds (eyes) sit close to the soil surface; planting too deep can reduce blooming. Space plants so mature clumps have room to fill out, and keep competing tree roots at a distance. In rainy weather, large double flowers can become heavy, so a discreet support ring or staking can help keep blooms upright and tidy.
After flowering, remove spent blooms if you want a cleaner look, but keep the foliage through summer so it can recharge the roots for next year. In fall, cut foliage back to the ground and clean up debris. With patience during establishment, you can expect a long-lived plant that improves with age.
