Quick Summary

Bladder senna refers to shrubs in the genus Colutea, belonging to the pea family (Fabaceae). These plants are native to the Old World and are characterized by their yellow flowers, which are followed by inflated, bladdery pods.12

One notable species is Colutea arborescens, a European shrub cultivated for its ornamental flowers and pods, and as a food source for wildlife. Another is Sutherlandia frutescens, a shrub from southern Africa also known for its inflated pods. While some senna species are used medicinally or for tanning, bladder sennas are primarily ornamental.12
