Paeonia, Chinese Peony, Garden Peony 'Tokio'

Per the 1928 Lee R. Bonnewitz Iris and Peony catalog of Van Wert, Ohio:
TOKIO (Japan). A very large pink Japanese Peony blooming o...Read Moren tall plants, producing excellent quality of show blooms, inferior only to TAMATBAKO and AMA NO SODE. The plant has strong stems, is very vigorous, and produces good laterals, making it a perfect landscape variety, and we believe that all commercial growers will be wise to include it in their lists. In rainy seasons some of the staminodes turn black, and in this respect it is inferior to TAMATBAKO, but it is so far superior to all other pink Japanese Peonies we have ever seen except TAMATBAKO and AMO NO SODE, that we are sure it will be in excellent demand for many, many years $6.00

Per the APS website:
TOKIO (Origin unknown) - Jap. - Pink - Midseason. Introduced by Dessert, 1910. Tall. Bitter medicinal odor. Large, cupped, waving guard-petals of dull rose-pink; center composed of large, loose staminodes, narrow at the base with wide tips tinted pale yellow and stained pink on the upper half, with buff edges; carpels green, white at base, with pale pink tips. Vigorous; fairly floriferous; strong, stiff stems. Dark broad foliage. An excellent variety, very similar to, but undoubtedly inferior to Tamate-Boku, from which it is distinguished by taller growth, slightly color, and pinkish carpels.
