What is it?

It's growing in the space that used to be a vegetable garden, and which now plays host to whatever can get its roots established.  That includes naturally-occurring weeds and grains that sprout from uneaten bird seed.  I don't think this is related to either of those, though.  Time to call on Google Images.

Later: OK, everyone who had Solanum rostratum may come pick up your prize,  namely:  my eternal admiration.  Now, how about that insect perched on top of it?
