Theresa Griesbach on peonyaddicts 2007:

Mother Teresa. Seidl. 2007. Advanced generation lutea hybrid. A Bill Seidl introduction, white semi-double to full double flowers on a strong plant, rich red stems and darkly tinted leaves, beautiful. Foliage is black-red in spring turning dark green is summer and then red again in fall. Cold hardy stems. Strong upright grower that does best in an open and airy situation to prevent disease. Easily grafted and grown. No fertility. (Anna Marie x Shintenchi).
