White sua flowers (Dalbergia tonkinensis), considered a symbol of March, are blooming in profusion on Hanoi’s streets after starting a bit early this year. 

The city has more than 1,400 white sua trees, mainly on Phan Dinh Phung, Hoang Hoa Tham, Giang Vo, and Thanh Nien streets.

The flowers are associated with the change of seasons from winter. This year, they began to bloom in February, earlier than usual.

"Hanoi is beautiful at any time of the year, but I prefer when the white sua trees shed their leaves and start blooming white," says Giang Trinh, one of the two authors of this series of photos.

White sua flowers grow in clusters of 7-9 mm and their fragrance can be felt by passers-by below. They only bloom once a year for around a week.

For poets and musicians, sua flowers honor the eternal love of couples and are a source of inspiration for their works.

For Hanoians, white sua flowers have become an enduring symbol of the capital and the coming of summer.

Their beauty provides plenty of inspiration for photographers.
