Mystery Yard Plant with Folding Leaves: Likely a Weed, Not a Houseplant

The expert specializes in houseplants and suspects this volunteer yard plant (6 oblong leaflets per stem, folding at dusk, yellow flowers in August, SE Pennsylvania) is a weed or bird-dropped seed. Not recognizable as a common houseplant.

Recommendations:

• Send photos of open leaves and flowers for a tentative ID.
• Consult the local county extension office—Master Gardeners can identify it quickly, possibly with a site visit.
• Check neighbors' yards for the same plant.
