The flower markings look more like Physalis to me. http://www.nku.edu/~herbarium/Taxonomy/Solanaceae/Physalis/Physalis.shtml

 

Is this the edible kind?

 

I couldn't say. I am not even that sure about the Genus. If it's a plant you will leave, it will be interesting to see the fruit. I certainly wouldn't eat anything that looked Solanaceous unless I had a positive ID.

 

That is for sure a physalis, so you probably got the genus correct :)

Yes I will be leaving it until it matures. I let weeds grow in my yard, because unlike most people, I am smart enough to know that some plants are edible and can be used for daily food, it is always of a better choice frugally than to go to the store.
