The strategy of early spring plants (Flower Calendar, February 25th issue), and the Flower Calendar video show the blooming of the dogtooth violet.

"Flower Calendar" is a news feature that reports on the seasonal flowers that can be seen at Inokashira Park Zoo.

In early spring, insects begin to move in search of pollen and nectar, helping to pollinate the flowers.

Special feature Flower calendar video

The characteristic feature of the dogtooth violet is that it blooms facing downwards, with its six petals strongly curved back.
In line with the ecology of the insects that help with pollination, the flowers open when the temperature reaches around 15°C on sunny days, and close in the evening or on bad weather days to prevent energy loss and ensure efficient pollination.
