bigleaf hydrangea called "Sumida Fireworks"?
The other day, when I was walking in the Higashinihombashi area, I saw a signboard of "Sumida Fireworks" on the planting beside Nihonbashi Junior High School in Chuo Ward. This is a corner where it was well-known as Ryogoku Hirokoji during the Edo period, and the "Sumida River Fireworks" was launched and crowded. According to the explanation in the explanatory version, a kind of bigleaf hydrangea says, "ornamental flower jumps out like fireworks in a star shape." I wanted to know who named it, and I held a smaphor over the QR code on the information board.
"It is said that the hydrangea collection researcher Takeomi Yamamoto found it in the garden of a craftsman in Yokohama in 1977 and announced it under the name "Fireworks Hydrangea." There is no information about the gardener in the garden, and my history is unknown. "Sumida Fireworks" is the name of sale by Sakata seeds. ”
A native Japanese species?
Also,
"In Siebold's Japanese Botanical Magazine, there is a picture of bigleaf hydrangea with a long flower pattern of ornamental flower. Yamamoto was not confident that there was such a hydrangea in Japan. The discovery of this variety resolved the questions and gained great excitement. ”
Yes, it was. That means that Siebold is a native Japanese species that also focused on? So why are you here as the right person in the right place? Also, on the information board, the time of the flower was written as "early summer", and I visited several times, but until now I could not feel the sign that the flower would bloom at all. Hydrangea such as temples is about to pass. Therefore, I asked the Chuo-ku Environmental Civil Engineering Department Water and Green Division, which may be managed under no good condition.
Planting on Miyuki Street
According to the section, following Nihonbashi Junior High School, the planting along Miyuki-dori (the Emperor Showa was visited to observe the reconstruction situation after the Great Kanto Earthquake) was divided into two times, last March and this March. It is said that it was planted scattered along with other plants and planted. What I found was planted in March this year, and it seems that it was still young for the flowers to bloom. The other day, when I visited the site and looked for a place that was planted last March, there was a "Sumida Fireworks" with flowers. However, it was hard to find that most of them were too busy and some flowers remained. As far as I count, there are 12 places where "Sumida Fireworks" was planted. Next year, I would like to see the "Sumida Fireworks" that blooms all at once and blooms vividly.
