The Roubai trees are blossoming in our garden.

Hello.
This is May in Japan.

The flowers of Roubai are in bloom in our garden.

These are Roubai trees.
Roubai means Japanese allspice.
It is written in Japanese as 蝋梅. 

The Roubai trees bloom from January to February in Japan.
The flowers are yellow.

The Roubai flowers are a Japanese winter tradition.
It is a very beautiful scenery that the yellow flowers bloom in white snows.
