What is palash.
Palash and Tesu are same - this is what was used in holi originally.
We are especially excited to learn about the beautiful palash blossom, also known as Flame of the Forest and Tesu. Butea monosperma is an Indian native that makes a marvelous orange-yellow dye. Suited to the season, the palash tree flowers in March. Its blossoms look like lively flames.
Legend says that Lord Krishna used to play Holi with Tesu flowers, so there you have it. The flowers are soaked overnight in water and can also be boiled to obtain a fragrant yellowish orange colored water. The dried flowers can be dried and powdered for a orange powder.
