The flowers of the golden shower trees, scientifically known as Cassia fistula, are beginning to bloom and fill the streets of Hanoi with a vibrant yellow colour.
 

Each branch holds around five buds which contain oval shaped petals.

The yellow buds form in bunches measuring between 20 and 40 centimetres.
 

The golden shower is the national flower of Thailand.
 

Together with bang lang, the crape myrtle, and phuong vi, the flamboyant flower, golden shower trees help make the summer more colourful and the streets feel far more poetic.

The flowers can be seen in full bloom from May until July.
 

The streets look increasingly beautiful as they are adorned with the yellow blossoms.
 

Here are some photos of the bright yellow flowers on the streets:
