My son has his own garden bed in our community garden plot. For the last two years he has only planted Giant Sunflower seeds in his garden bed. This year he planted Bottle Gourd seeds along with a new variety of Sunflower seeds. My son plans to make his own birdhouses and musical instruments from the gourds he grows (we will consult the Gourd Reserve when it comes time for harvesting and drying the gourds). He planted Magic Roundabout Sunflower seeds, a hybrid sunflower that branches out and produces more than one flower per plant through summer into fall. I plan to brighten our house with cut sunflowers this summer and fall!
Everything from our garden plot does not need to be edible to be useful!
