Need Help with ID

I have quite a bit of something growing in my yard and I wasn't able to figure out what it was by Googling. I'll attach pictures.

I'm in Oklahoma, zone 7. It's got vaguely heart shaped leaves, little spherical seed clusters and grows well in the shade were hardly anything else can.

I'm kinda hopeful that it's edible/medical because it loves growing in really low sun and no irrigation.

I'd really appreciate the help if anyone knows it.

Your plant might be in the Sida genus. I have not been able to find a picture with the seeds.  

Sida

Some varieties in the Sida genus are medicinal.  

"Sida has historically been a wastebasket taxon, including many plants that simply did not fit into other genera of the Malvaceae. Species have been continually reclassified.[2] The circumscription of Sida is still unclear, with no real agreement regarding how many species belong there. Over 1000 names have been placed in the genus, and many authorities accept about 150 to 250 valid names today.[2] Some sources accept as few as 98 species.[6] There are many plants recognized as Sida that have not yet been described to science."

Your County Extension office might be able to help with your identification.
