10/ Titan sunflower. I will not grow these again. 

They grew fine, but they didn’t produce many viable seeds for some reason, even though they were well-visited by pollinators. It might be because they weren’t grown in very good soil and got no fertilizer (the Tepary did fine with the same conditions). They took a major beating in the storms. I never watered them except to start the seedlings when there was no rain.
