Identification
Morphology
Senna occidentalis is a self-supporting plant that typically takes the form of a sturdy shrub. Depending on its specific environmental conditions, its stature can vary significantly across different habitats. While some specimens may remain quite small at just 0.15 m, others reach a more substantial minimum height of approximately 1.17 m. For those growing under optimal circumstances, the plant can continue to expand until it reaches a maximum height of 5 m. This wide range of size allows the species to adapt effectively to various ecological niches.
