Syn.. Youmefour & RIE04

A cultivar characterized by broad upright habit, large medium-green leaves, flowers that are yellow-green to dark pink in color, and unique inflorescence development.  Clusters of Pale pink, very symmetrical double flowers, similar in shape to a minute Camellia.   It originated when the inventor assembled a collection of unnamed and unreleased hybrids from a sequence of deliberate pollinations involving the following cultivars, all unpatented, and available in  Japan: Hydrangea macrophylla `Otafuku`, Hydrangea macrophylla, `Yamaajisai`, and Hydrangea macrophylla `Fijinishiritaki`. The inventor did not record which variety was used as male parent and which as female parent. In May 1993, the inventor carried out a deliberate pollination between one unnamed plant from the inventor’s collection as female parent and the variety Hydrangea macrophylla `Sumidanohanabi` as male parent.
