» English Description

Williams & Thompson, 1950, American Camellia Yearbook, p.46: Large, fine white, varying from semi-double to irregular double, 10-12 cm across. The outer petals are about 5 cm long and edges notched. The inner part of the flower is an irregular mass of various sized petaloids mixed with stamens. The leaves are mid-green, 9 cm x 7 cm, veins prominent, light green, coarse serrations. The cultivar was registered with the SCCS as a seedling from (Daikagura x Nobilissima) x (Nobilissima x Shiragiku) However according to other accounts it was obtained from Mr Uyematsu of the Star Nursery, either as a seedling or seed from Japan in about 1922. Nuccios distributed it under the name 'White Daikagura'. Syn­onyms: 'Daikagura White', 'White Daikagura'. Orthographic errors: ‘Joshua A. Youtz’, ‘Joshua R. Youtz’, ‘Joshua Yountz’, ‘Joshua A.E. Youtz’. Abbreviation: 'Joshua Youtz'. For colour photos see Fendig, 1951, American Camellia Catalogue, and Nuccio's Catalogues 1951 to 1957. It is very similar to Shiro-daikagura and carries the same synonyms. Chinese synonym: 'Yaoshuya', spelling later changed to ‘Yueshuya’.
