I grow the BURPEE brand Cosmos that you buy in Home Depot and Lowe's in the Spring. There are usually only One (1) variety of Cosmos sold in seed packets in stores, I didn't know there were "Varieties" of Cosmos. For specialty type seeds, I would have to order them online via a special
Seed Supplier. I don't use fertilizer at all. It was the Spring Rains followed by the intense Sunlight
that caused my Cosmos to reach 7-ft in height.
