Buckwheat (scientifically known as Fagopyrum Esculentum) is a plant with clusters of small pinkish white flowers and edible triangular seeds.

H’Mong ethnic residents grow two crops of Tam giac mach every year, as it also blooms between April and May. The flowers are sensitive to sunlight, turning from white in the early morning to pink in the afternoon.

Buckwheat creates striking sights when blossoming, making it a tourist draw in Ha Giang, as well as neighbouring mountainous areas such as Lao Cai Province.

The provincial Department of Culture, Sports, and Tourism will organise the festival in Dong Van district, as instructed by the Ha Giang People’s Committee.

Various activities will be held as part of the event such as a H’Mong panpipe festival, a tourism fair and a photo exhibition about the Dong Van Karst Plateau, which was recently recognised as a member of the Global Network of National Geoparks for the 2015-2018 period.
