2021 Tallest Sunflower competition

I'm debating with myself whether to sow some specially for the competition. Two sides are warring, I don't need any sunflowers, nowhere to put them as they're growing or when they're tall. Then the competitive side kicks in. I think on the whole, as I'm way behind other's sowing dates I might just bow out of this one, but then again once I'm in the gh with the pkt of seeds I might relent. They don't call me wavy Mavis for nothing
