Cosmos will bloom in approximately 50 to 55 days after germination. So not sure the variety is that much of a big deal. If you wish, go to the site of a retail seed seller (Burpee, Johnny Seeds, American Meadows, etc.) and give them a ring. Keep in mind that growth is also affected by weather, soil temperature, and germination speed.
