Peonies are perennials and are known to live for decades, even generations. The blooms are outrageously beautiful, producing lush, glossy green foliage all summer long. Foliage turn purplish or gold in the fall and is as stately and dignified as any shrub. They are somewhat more expensive to propagate, but well worth the investment in your garden.

These peonies are best grown in pots sized 6-10". The roots can be pruned back to fit the pot, but do not cut off the eyes. It is important to cover the entire root with about 1.5-2" of soil since the eyes should never dry out. Good soil drainage and airy soil is best for good root development. They can be planted anytime from September through March. Drench well after planting, never letting the soil dry out during the growing process. They like being fertilized and need at least 8 weeks minimum of wintertime temperatures. Maximum light will prevent stretching of flower stem.
Warmer temperatures encourage root development, while cooler temperatures encourage shoot (eye) growth. To ensure all shoots develop, follow cooling requirement.
