Every summer I cannot resist planting giant sunflowers. They are like instant trees and completely alter the landscape. Last summer, I used them as the "posts" of my cucumber trellis, and they were great. Plus it helped keep them rooted in heavy wind days, since these giant flowers have rather shallow root systems.
In the end, we were able to have sunflowers for sale at the farmer's market as bird feeders, and several on the porch for the same reason. :) We also harvested the seeds and salt-brined and baked them. They make sure yummy snacks; except for one problem... half of them are empty! My neighbor suggested I market them as "diet" sunflower seeds since they have half the food/calories. :D
I think this year I will try to hand pollinate them and see how they do...
