Cassia bicapsularis
Showy Senna
This subtropical shrub has abundant bright yellow flowers in late fall. It is evergreen in zone 10 and stem hardy in zone 9. The seeds are said to be poisonous but not deadly. In zone 8 it may freeze back but after cold kills the tops it can be cut back and mounded with coarse sand and mulched with pine straw. As weather warms, remove this covering to allow new shoots to emerge. Given rich soil and ample water, these plants will thrive during hot summers and bloom around Thanksgiving time. Riffle, in The Tropical Look says this plant is widespread in the American tropics but the exact native range is uncertain.
