Can anyone help with my Blue Dawn morning glory? This is the third year I've had it. Every year it grows back in the same spot in my yard. Same soil, same sun during the day. It has always opened early morning and closed at dusk. It started getting some blooms about two weeks ago and they are opening same time, but closing around noon now, just like regular "morning" morning glories. Their environment is the same as other years and they are healthy and covered in buds. Anyone ever heard of Blue Dawns doing this? Thanks for any help.
