Early-midseason blooming DOUBLE flowers are white with a blush pink center and sparse red-pink flecking, 12cm (4.7”) in diameter, upward facing, and average one per stem. Fragrance noted. Guard petals are flat and rounded, and average 3.5cm (1.4”) in width. Possesses two smooth, pale-green carpels with light-pink stigmas. Stamens are 1-2cm (0.5-0.75”); filaments are yellow with yellow tips and anthers. Produces both pollen and seeds. Plants reach 60cm (23.5”) at maturity, and carry somewhat broad, pointed, green foliage. Growth habit is low and broad and does benefit from mechanical support. Named for Zhejiang where the plant has been noted to grow well, and where the Jiangnan region exists south the the Yangtze River. Here, silk bamboo is a symbol of the region and its musical instrument, and so the cultivar was named ‘Jiang Nan Si Zhu’.
