Senna lindheimeriana

Senna lindheimeriana, the velvet leaf senna, is a species of flowering plant in the family Fabaceae. It is native to the US states of Arizona, New Mexico, and Texas, and to eastern Mexico. A perennial typically 1.5 m tall, it is hardy to USDA zone 8a, and is recommended for xeriscaping and for feeding birds, butterflies and bumblebees. It is thought to be lethally toxic to livestock, but is so foul-smelling and unpalatable that only starving mammals will consume it.
