Yan Long Zi means Purple Haze at Twilight. Depending on weather and soil conditions this fabulous tree peony is anywhere from merlot red to nearly purple. With a full double crown, it is a peony that makes people who don’t even care about plants and flowers stop to ask what it is. These blooms are very large (6x3) upright, and densely fragrant. With long-medium leaves, on a small sized bush it is the perfect tree peony for a small yard.
