I grew this about 10 years ago when I had only a balcony. It was too big so I never bothered again. Now that I have a little garden, I decided to grow it again and ordered seeds just last week. I am experimenting with a few annuals as struggling to keep things going through the severe heat of summer only to see them succumb is frustrating. Over the summer I have a framework of tried and trusted perennials that give me some colour.
Unfortunately, this year's annuals were a disaster. Almost everything destroyed by a violent hailstorm which smashed the seedlings to pieces and then left them covered in ice for a couple of hours - and that was in June!
