Some upright plant in fabaceae family

bostedo(8a tx-bp-dfw)August 21, 2013

This came up in a sunny spot in a Dallas, TX area lawn. Much more upright than the vetches that are common here. No flowers (or thorns) yet. Currently about 2 ft tall. Any ideas what this may be? TIA

Sesbania drummondii or similar species.

Oh... "poison bean" ... nice. Not seeing many strengths for urban residential use unless needing to remove lead from soil. Will try to keep it alive in the pot until it flowers, but will stick with the similar look of Lindheimer's senna for the garden. Thanks!

Here's what the small flowers look like. Maybe sesbania herbacea?

Pods are the easiest to ID. S. herbacea(exaltata) is roundish, S. drummondii is winged.

Thanks - Will post again if it manages to set seed.

Here's the pod; not really winged or roundish... more "pea-ish". Does that help with an id?

S. exaltata would be my guess. It's rounder in cross section not winged and not single seeded.

What a pretty bloom. Much nicer (IMO) than the S. drummondi that I've seen growing in the exposed shore areas around the lake.

Sorry to bump, just adding a photo of the mature pods because they look considerably different than the earlier one I posted. The synonym 'bigpod sesbania' now makes sense. They are just now starting to turn brown.
