The Kochia field is the highlight of Hitaki Seaside Park
In autumn, about 32000 of Kochia balls and 2 million flowers of cosmea attract visitors. Kochia gradually begins to turn red in late September and gets burning red around the middle of October. (Varies every year depending on weather conditions.)
Kochia balls swaying by the wind look very kawaii.
Kochia is called Houkigusa, means “broom grass” as dry Kochia is used to make brooms. Since the Kochia is an annual (plant), they are removed from the field in winter. In early summer the seedlings are planted by hand, one by one, all over the field.
The hill is covered with Nemophila (Baby blue eyes flowers) in Spring
Before Kochia seedlings are planted, Nemophila (Baby blue eyes flowers) are grown in the field. The hills all covered with the blue flowers are also a popular attraction of the park. The best season of the Baby blue eyes will be around early May that falls on Golden Week, the consecutive national holidays.
