Danglepod (Sesbania herbacea), a very swift-growing weedy native annual, now graces the 3-14-2015 wildflower planting at the (Pelican Island) Audubon House. Driven by the recent rains, this plant is now taller than I am in some places on the property.
Also known as hemp sesbania, bigpod sesbania, coffee-weed, tall-river hemp and bequila, this member of the pea family, Fabaceae, has compound leaves with 20 to 70 leaflets. Its yellow dangling flowers are speckled with purple and give way to long thin pods which contain a copious number of very viable seeds.
This plant is thought to be toxic to livestock, especially cattle, due to the saponins that it contains. This plant volunteers freely in moist, disturbed places where it sometimes forms a monoculture.
