Buckwheat flowers typically bloom from late September to December. What's special about this flower is that its color changes over time. In late September, buds begin to appear, blooming sporadically in a pristine white. By October and November, the flowers begin to bloom profusely on the hillsides and valleys, creating dreamy fields of pink and purple flowers throughout the mountains of Ha Giang. And by December, at the end of the season, the flowers gradually turn a deep pink.

Buckwheat flowers bloom on hillsides, in rice fields, along roadsides, and beside the verandas of ancient houses. The green of the trees and mountains of Ha Giang blends with the pink and purple hues of the flowers, creating a breathtaking scene, as if you've wandered into a land of fairy tales.

Buckwheat flowers bloom profusely in the Suoi Thau meadow, creating a stunning landscape. This place is known as the "Switzerland of Vietnam".
