Thirsty
"Third year for these, and they can't hang here in dry windy Wyoming(which is odd because they're listed as native and common in my county, must only occur in riparian areas, because I've never once seen these in the wild). They do bloom at a very appropriate time in about mid August, so that's nice, and they are a beautiful perennial sunflower, but…. I had to water these constantly this year and they were always struggling, the plant in the photos is about 2 feet, and the other only got about six inches tall this year. Wouldn't recommend to anyone receiving less than about 20"" precipitation annually, unless you want to provide consistent supplemental water(might do good in a rain garden with some shade too, but not dry full sun)."
