On September 27, the Tokyo Regional Meteorological Observatory released one of the biological seasonal observation information "Japanese pampas grass Flowering".
18 days later than normal and 4 days later than last year.
The ears of Japanese pampas grass are a collection of flowers. The first day when the number of ears extracted from the leaf sheath is estimated to have reached about 20% of the total expected ears, is called "Japanese pampas grass's flowering."
Along the Sumida River Terrace on the side of Toyomi Bridge, Japanese pampas grass is fighting against the wind against the backdrop of Eitai Bridge.
Japanese pampas grass is included in the observation item because it is suitable for examining the progress of the seasons, and it is said that there is a correlation between the flowering of Japanese pampas grass and the temperature, and that the flowering tends to slow down when the temperature rises.
Although there are regional differences, the flowering of Japanese pampas grass tends to slow in recent years, and the relationship with global warming seems to be attracting attention.
By the time the flowers open, the ears glow softly white and silver, and when the season deepens, they shine golden.
The best season for watching Japanese pampas grass is when it shines from silver to golden.
In particular, it is wonderful to sway in the sunset and sparkle golden.
In addition, there is the same golden ogi as a plant similar to Japanese pampas grass, but Japanese pampas grass has a long spine-shaped "tagram" protrudes from the tip of the spike, while the ogi has no awn.
