I found this growing in a horizontal seam on a vertical wall and wondered how the seed got in there. Very healthy looking and large pretty flowers. Is it Black Nightshade? The flowers seem too big. I posted to the Bug forum about the creature atop the fruit.

It could certainly be Solanum nigrum.

It is Solanum americanum, Black Nightshade.

I was thrown off by the white flowers. They are always lavender in Central California.

According to Dave's link, S nigrum is a synonym.

Quite a few synonyms and a very mixed up complex. COL still has S. nigrum as an accepted name. The fruit on this plant hang down which seems to be part of keying it out. I had another look at it today. I'm hoping it will survive until some of the fruit is ripe and get a few more details about it's anatomy.
