I enjoyed YELLOW and GREEN cherry blossoms yesterday at Hama-rikyu Gardens in Tokyo. The yellow one is Ukon (Cerasus Sato-zakura Group ‘Grandiflora’ A. Wagner) in this post and the green one is Gioiko (see this post)! Ukon and Gioiko cherry trees are both late bloomers, so luckily I was able to enjoy both blossoms.
Ukon cherry blossoms are popular for their yellow flowers whose core turns red before they fall, creating a beautiful color contrast between yellow, green and red. The flowers are multi-petalled and freshly gorgeous!! The name Ukon, meaning turmeric, is after the yellow color of fabric dyeing with turmeric. The chloroplasts of Ukon and Gioiko both contain carotenoid (i.e., yellow pigment) and chlorophyll (i.e., green pigment) but Ukon's contain less chlorophyll, producing greenish YELLOW flowers while Gioiko's contain more chlorophyll, producing yellowish GREEN blossoms.
