|'Gay Paree' has light green leaves, and in midseason, bears large, Japanese-type, deep cerise-pink flowers, with shell pink centers.
Peonies are herbaceous perennials arising from thickened tuberous roots. Largely invisible, hidden underground most of the year, they are quite spectacular when they emerge. In spring, purple divided leaves push through the soil, rapidly unfurling and turning green. The fine foliage is attractive in its own right, the flowers are very showy, coming in three types: single or semi-double, Japanese, with one row of petals and a large center, and highly ruffled double forms. The colors generally range from white, light pink to magenta and red. Plant peony tubers in the fall, 1 to 2 inches deep, in well prepared garden beds, with organic matter worked in. They respond well to a yearly fertilization, and addition of bonemeal. It is best to leave them undisturbed, dividing them infrequently.
Botyritus can be a problem during humid spells.
Peonies are one of the longest living herbaceous perennials often found in older gardens, for once established they will survive neglect. One hundred year old peonies are not uncommon.
