Cosmos blossoms at play in the open sky.

Cosmos is sown, not wild: its date depends on the variety, the sowing schedule and the people who run the field. Engaru in Hokkaido advertises mid-August to late September, Uminonakamichi in Fukuoka mid-October to early November. There is no national front to follow.
How long it lastsHeat or a changed sowing plan can move a field by weeks. At Bihoku Hillside Park in 2026 one variety peaked in August and was over by early September, before its own festival, and the park cleared the plants.
