Cassia Siamea, commonly known as Siamese Senna or Thai Copper Pod, and Cassia Florida (Yellow), are two closely related species of flowering trees that belong to the Fabaceae family. These trees are renowned for their ornamental value, vibrant yellow flowers, and a range of practical uses. Below is a detailed description of these two species, including care tips and various uses.
Cassia Siamea (Siamese Senna or Thai Copper Pod):
Description:
Cassia Siamea is a medium-sized deciduous tree that can reach heights of up to 25 meters. It is native to Southeast Asia and is characterized by its spreading crown, pinnate leaves, and distinctive yellow flowers. The tree produces flat, brown seed pods, and its bark is smooth and grayish-brown.

- Watering: Regular watering is necessary, especially during dry periods. However, the tree is somewhat drought-tolerant once established.
- Sunlight: Full sunlight exposure is ideal for Cassia Siamea. Ensure the tree receives plenty of direct sunlight for healthy growth.
- Pruning: Prune to maintain shape and remove dead or diseased branches. Cassia Siamea responds well to pruning and can be shaped into a more compact form if desired.
Uses:
- Ornamental: The tree is valued for its decorative qualities, especially when in bloom. The vibrant yellow flowers add a splash of color to gardens and landscapes.

Cassia Florida (Yellow):
Description:
Cassia Florida, also known as Yellow Shower, is a smaller tree compared to Cassia Siamea, typically reaching heights of 6 to 8 meters. It is known for its profusion of bright yellow flowers, which give it a stunning appearance when in full bloom.
Care:
- Climate: Cassia Florida thrives in warm climates and is well-suited to tropical and subtropical regions.
- Soil: Well-draining soil is preferable. The tree can adapt to various soil types but performs best in fertile, loamy soil.
- Watering: Keep the soil consistently moist, especially during the growing season. However, ensure that the soil does not become waterlogged.
- Sunlight: Like Cassia Siamea, Cassia Florida requires full sunlight for optimal flowering and growth.
- Pruning: Prune to shape the tree and remove any dead or crowded branches. Regular pruning can encourage a more compact and attractive form.
Uses:
- Ornamental: Cassia Florida is primarily cultivated for its stunning yellow flowers, making it a popular choice in gardens, parks, and along streets.
- Bee Attraction: The abundant flowers attract pollinators, especially bees, making it a beneficial addition to gardens that support local ecosystems.
- Landscaping: The tree is often used in landscaping to provide a burst of color and enhance the visual appeal of outdoor spaces.
In summary, both Cassia Siamea and Cassia Florida are beautiful trees with ornamental value and practical uses. Proper care, including attention to soil, water, sunlight, and pruning, will contribute to their health and visual appeal in landscaping and gardens.
