Exquisite, early blooming, easy: Tree Peonies are so beautiful they seem difficult to grow. Ensure the graft points are thoroughly buried, keep them watered well in summer, feed them with a bloom-boosting fertilizer, give them 6 hours of sun a day, and within a few years you'll have plants loaded with flowers.
Double white petals have a slight cranberry tinge at the very center. A mustard-yellow center perfects the picture.
