Hello again, guys (once again, generic)
An advantage of those weird flowers with apparently only one kind of flower part is that they make it possible for a zinnia to take on the form of an onion flower.
By "onion flower," I mean the actual flower of an onion, not the delicious dessert. There are already flowering varieties of onions with near-spherical flowers. Onion flowers are attractive for that reason and come in various colors. I think it would be interesting if there were a variety of zinnias with spherical flowers. Genetic engineering could make them glow in the dark in many colors, although many people would balk at GMOs. I guess you can't have everything.
