How to identify Gulabi Siris
Identify Gulabi Siris by combining habit, leaf characters, flower or fruit details, location, and its family pattern. Do not rely on one feature alone.
- Look for a tree habit.
- Check the distinctive field mark: Massive spreading umbrella canopy, leaflets fold at dusk (rain tree).
- Confirm leaf shape: Feathery bipinnate leaflets.
- In season, compare flowering and fruiting time: January-July.
- In India, compare location records such as Maharashtra, Tamil Nadu, Karnataka, Telangana and nearby regions.
- Confirm it sits within the Mimosaceae family pattern, then compare close relatives before deciding it is Gulabi Siris.

Gulabi Siris in India
This wide-canopied tree, known as गुलाबी सिरिस Gulabi Siris (Hindi), தூங்குமூஞ்சி (toongumoonji) (Tamil), నిద్ర గన్నేరు (Telugu), ಮಳೆಮರ Malemara (Kannada), മഴമരം (Malayalam), पर्जन्यवृक्ष (Marathi), is planted almost everywhere for its dense shade. Samanea saman is grown across Maharashtra, Tamil Nadu, Karnataka, Telangana, Kerala, Andhra Pradesh, especially along roads, in parks and on plantations for shade.
Uses
It's planted almost entirely for shade, thanks to its exceptionally broad, umbrella-like canopy, and its wood has also been used for furniture and carving in some regions.
How to Identify Gulabi Siris
A large, wide-spreading tree with a flattened, umbrella-shaped canopy far broader than it is tall. Leaves are bipinnate and fold up in the evening or before rain — the source of its 'rain tree' name. Flowers are pink powder-puffs with long silky stamens, followed by long, dark, sticky-pulped pods.
Frequently Asked Questions
- What is Rain Tree called in different Indian languages?
- गुलाबी सिरिस Gulabi Siris (Hindi); தூங்குமூஞ்சி (toongumoonji) (Tamil); నిద్ర గన్నేరు (Telugu); ಮಳೆಮರ Malemara (Kannada); മഴമരം (Malayalam); पर्जन्यवृक्ष (Marathi); Biliti siris (Bengali).
- Why is it called the 'rain tree'?
- Its leaflets fold shut in the evening and before rain, and the tree is also said to 'drip' from sap-sucking insects overhead, both contributing to the common name.
- Why is its canopy so wide?
- It naturally branches low and spreads broadly rather than growing tall, giving it one of the widest canopies of any commonly planted shade tree.
