I grew a couple of sunflowers over summer, but other than being good for photos they weren't that great! Hardly any of the seeds took, the few that did got eaten by caterpillars and the two that made it seemed to need a lot of water or they went all sad and droopy. But I enjoyed watching them unfold and open up. They lasted about a week and now they are all crispy and finished. I'll scattered the seeds and see what happens but I am not going to try very hard with them again!
