What Is Cassia Fistula?
Cassia Fistula, commonly known as the Golden Shower Tree, is a tropical tree native to South Asia. It’s renowned for its cascading clusters of bright yellow flowers that appear in late spring or early summer. The tree can reach heights of 30 to 50 feet and has a broad, spreading canopy that provides ample shade. Its lush foliage and striking flowers make it a popular choice for ornamental landscaping.
How to Grow Cassia Fistula from Seed?
Growing Cassia Fistula from seed can be a rewarding process if done correctly. Start by soaking the seeds in water for 24 hours to soften their hard outer coating. After soaking, sow the seeds in a well-draining potting mix, ideally a mix of peat, perlite, and sand. Plant the seeds about an inch deep and keep the soil consistently moist but not waterlogged. Place the pots in a warm, sunny location. Germination usually takes 2 to 4 weeks. Once the seedlings have grown strong enough, transplant them into larger pots or directly into the garden.
How to Make Cassia Fistula Bloom?
To encourage blooming, Cassia Fistula needs the right conditions. Ensure it receives plenty of sunlight, as this tree thrives in full sun. Proper watering is crucial; while the tree is drought-tolerant, it benefits from regular watering during dry periods. Fertilize the tree with a balanced fertilizer to provide essential nutrients. Additionally, ensure good drainage to prevent root rot, which can hinder blooming. Regular pruning to remove dead or damaged branches can also help the tree focus its energy on producing flowers.
How to Prune Cassia Fistula Tree?
Pruning Cassia Fistula is essential for maintaining its shape and encouraging healthy growth. The best time to prune is after flowering, as this allows the tree to focus on new growth.

Always use sharp, clean pruning shears to make clean cuts, and avoid cutting back more than one-third of the tree at a time to prevent stress.
Is Cassia Fistula Plant Poisonous?
Cassia Fistula is not highly toxic, but caution is advised. The seeds and leaves contain compounds that can cause mild gastrointestinal distress if ingested in large quantities. It’s best to keep the tree out of reach of small children and pets. Always consult a healthcare professional if there is any concern about poisoning or if any part of the plant is ingested.
