About Sickle senna
Senna tora, commonly known as 'Sickle Senna' or 'Sickle Wild sensitive-plant', is an annual herbaceous plant belonging to the Fabaceae family, native to tropical regions. It is characterized by its pinnate leaves with oval leaflets and bright yellow flowers clustered in axillary racemes.

Care tips
It thrives in full sun exposure for optimal flowering. This plant is drought-tolerant once established, so watering should be moderate, allowing the soil to dry out between waterings to prevent waterlogging. It adapts to a wide range of soil types, though it prefers well-drained ones. A common mistake is overwatering, which can lead to root rot, as it is accustomed to drier conditions.
