I like them,but they don't like TX heat.You growing
them in pot outdoors would be the same as wintersowing them.I sowed some in the fall the 1st time I tried them.They we're in a pot under the eaves & did quiet well for the winter(being mild here...sorry)I would move them in for frosty nites& move back out mid-day.The next time I grew them (took a year or two for success again)they did poorly& were very short as in barely 2 inches tall but did bloom.
Try looking here.It is full of info on wintersowing& may help you figure the best way to go.(ME???I'd move pot to a milk jug& cut lid partway off so will still cover& let MN look after them.Wintersowing impressed me last me last year.) http://www.wintersown.org/
