We won't be taking part in the competition ourselves, but we planted a few different varieties this year to see how they compared.
Of course we've planted a few of the competition seeds Helianthus Kong, as well as one of our other favourites Mongolian Giant, and for the first time this year we're trying Titan, and Sunzilla which can grow up to 3 meters tall (10 feet) with a head that's a massive 45cm across (18 inches)!
Our oldest plants are around three weeks old now, so far they've made it through the wind and rain but we've lost a few to slugs!
We've put down plenty of grit and sand to try and keep them at bay - if anyone's having slug problems we posted some of the more popular methods for dealing with those savage beasts here on the blog last year.
