. . . but you can never leave.
I'm not sure what this little weed flower is, but it definitely looks like it wants to be the last place some little bug checks in . . . and out. It looks like a pitcher plant of some sort, but the flower is tiny, about 3/8 inch long, and the plant is huge, 3 feet tall. It's hard to believe that big old plant could get much nourishment from ingesting the tiny bugs that could get caught in the little flower, but maybe they are just dessert. Pretty though.
