I bought plants last year at the local garden center. They were bedding plants, I guess, which were grown by John's Greenhouses, LTD in Weatherford, TX. They were mixed colors and were called 'Happy Hour' (trademark). There were about three colors I tried to separate away from the others and the white was one of those. I attempted to overwinter them, but eventually they died. Then this spring these seedlings came up in those containers. So these white ones came from seeds furnished from the 'Happy Hour' plants that were white. The white ones have all bloomed white. The other two containers mostly ran true, but not quite. There were whites in both of them as well as some other colors.
