I have one that has been blooming for over a month. It was a volunteer. Every time I’ve tried to grow hollyhock, the plants suffered from rust – a common problem – which lessened the vigor and the bloom time. I deadhead the plants, at least the stems I can reach, to keep it from self-sowing everywhere. This may encourage it to bloom longer.
