I see 'suckers' in the thing's armpits - that tells me it's a veggie maybe?
Nightshade family? Could it be cucumbers?
I'd like to move it to a place on its own, but the bugs seem to be eating everything I put hin the ground this year, so I don't wanna' disturb it.
I know it doesn't belong in that pot with the others, but it's just darn interestin'.
