Autumn harvest observation event in Yoyogi Park on a cold, rainy autumn day




Unfortunately, it rained in Tokyo on Saturday, the first day of the three-day weekend. However, the rain was still a little light in the morning, so the Nature Exploration group in Tokyo City Guide Club held an observation event in Yoyogi Park with the theme of autumn fruits or nuts.
We don’t usually pay much attention to these small fruits, but if looking closely, I can see that Chinese hackberry, Scabrous aphananthe, and camphor trees are secretly bearing fruits.
Also, depending on the type of acorn, the way the fruit is formed and the shape and pattern of the cupule, also called a cap, vary, and when we understand the differences, we will feel a little proud. The autumn leaves in the park have started to change little by little, with flowering dogwood and winged spindle bearing red fruits, but most of the trees, including the maple, are still green.
The autumn leaves are a little late this year, but in a little while the leaves of the trees in the park will turn red and yellow and we will be able to enjoy them again, but I am a little worried about how the heat of this summer will affect the autumn leaves.
What surprised me a little was that the early-blooming Kawazu cherry trees was blooming out of season. Could this be due to the long, hot summer this year?
