The information above lists this plant as a biennial, but in my experience, it's one step worse than a biennial: a triennial (if that exists), blooming in its third year and then dying. Still, it's such a striking plant when it does bloom that it's worth it. Just have to remember to keep starting new plants every year, so that there's always a crop in bloom somewhere around the garden :-)
