There are three types of Thazhuthama plant – one has purple flowers while the other two have white flowers. In this post, we are looking at the one with the pink flowers. Its scientific name is Boerhavia diffusa.


Boerhavia diffusa grows by spreading on the ground up to about 2 meters in area with numerous branches and sub-branches. 2 to 3 leaves emanate from each node and these leaves differ in size. The biggest reach up to 4 cm in length while the smallest is barely 2 cm.

The tiny purple flowers form a cluster with 4 to 10 individual flowers in each. They appear opposite to leaf axils.

The fruits of Thazhuthama are round containing one seed which is brown.
