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, turning purplish or gold in the fall, as stately and dignified as any shrub. They are somewhat more expensive to propagate, but well worth the investment in your garden. Peony Sorbet is a real show stopper and in a class all its own, one of the most successful of its type. The flowers (5 in. to 7 in. size) have 3 layers of petals and the unusual pastel pink and cream colors change through the season as the flowers mature. 3 seasons of color, reddish spring foliage, pastel blooms in summer and purple bronze foliage in the fall.
