Morning Glories: Little Blue Guys, 0 by Seamus_tt

My parents have been following the progress of my morning glories eagerly, and even "playing along at home" with some vines of their own. They got a little surprise earlier in the year when, over in one corner of the yard, they found a whole bunch of these little blue guys growing where they hadn't done anything other than clear out some brush. I recently received an envelope from mom, containing this photo, and a bag full of seeds. Said seeds are small, black, and shaped like orange wedges, not at all pointed like the tricolor seeds I have seen/sown.

I can't tell a whole lot about the flowers and vines from the photos, other than that they seem to have heart-shaped leaves, no real yellow coloration to the throat, and that they make really small blue flowers.

So any ideas as to what variety I've got here?
