Amaltas in India

Amaltas drapes Indian summers in cascades of gold — अमलतास Amaltas (Hindi), கொன்றை Konrai (Tamil), రేళ్ల చెట్టు (Telugu), ಕಕ್ಕೆ Kakke (Kannada), Kani Konna (Malayalam), बहावा Bahava (Marathi). Cassia fistula is planted across Maharashtra, Tamil Nadu, Telangana, Karnataka, Kerala, Rajasthan as an avenue and garden tree, and its bloom (kanikkonna) is central to Kerala's Vishu festival.

Uses

It is grown above all as an ornamental for its spectacular hanging chains of yellow flowers. The long cylindrical pods and pulp have attributed uses as a traditional laxative in Ayurveda — described for information, not medical advice. It is the state flower of Kerala.

How to Identify Amaltas

A medium tree that flowers in summer with long, pendulous sprays of bright yellow five-petalled flowers. The leaves are pinnate with several pairs of leaflets, and the distinctive fruit is a long, cylindrical, dark brown pod that rattles with seeds.
