Senna Seeds - Herbal Plant for Home Gardens

Senna, botanically known as Senna species (formerly Cassia), is a group of flowering plants valued for their upright growth and bright yellow blooms. These plants develop as shrubs or small trees with pinnate leaves and produce clusters of flowers during the growing season. Senna adapts well to warm and tropical climates and performs best in full sun with well-drained soil. It is commonly used in garden beds, hedges, and landscape planting, where it establishes readily from seeds and tolerates dry conditions once established.
