I am interested in growing some "jack and beanstalk" size sunflowers on the west and south side of my home this year. I was wondering if anyone had any suggestions on seed type and should start now indoors or just plant in the soil around mid May to June 1st? Also do they like full sun and how moist should I keep them. I have never been able to grow them down here in Anchorage very tall although I grew some nice "Mammoth Grays" in Fairbanks, seven years ago. My friend's wife had some big ones a few years back but they were volunteers that fell out of the bird feeder. Go figure.
