The plant in the 2nd photo looks more like some kind of vine to me than a 4 o'clock; maybe a wild morning glory or bindweed?

I struggled for years trying to get 4 o'clock seeds to sprout, until I got some from a swap that grew just fine; I don't know what the heck the commercial seed companies are selling, but I don't think it's very fresh seed!
