Cherry blossom is three weeks of it. Flip through the other forty-nine — and watch what's in bloom move up and down the country.
The calendar is the way in. Underneath it sits the ordinary thing — search, filter by month or flower, and open any of the 412 spots.

About 500,000 sunflowers on four hectares, planted in three blocks so they open in turn, with a sunflower maze and a viewing platform. Entry is free; parking is paid.
