Notable characteristics: This variety is always a favorite with visitors to our garden, and we are very pleased to finally be able to offer this lovely cultivar. Blossoms slowly unfurl with a distinct, pale pink, cast. Petals change to white as the flower opens fully. Dark purple flares at the center are mostly hidden by the dense petal arrangement. Flowers are incredibly fragrant, one blossom will perfume an entire room! A very rare and choice tree peony.
