It doesn't state what zone but some of the flowers that are in the mix are Cheiranthus Cheirii, Chrysanthemum Shasta, Delohinium Consolida, Echinacea Purpurea, Rudbeckia Hirta. I hope this helps. I don't know the common names for these but I'm sure you can google them and see the zones they are for. Whatever the zone for them will apply to all of the ones that are in the mix. Thanks for asking :)
