Call them about the timing of when they will be getting their annuals. Zinnias like lots of sun and warmth. I'm an avid gardener and don't plant any summer annuals until after there is no threat of a frost. Years ago we had a killer frost on LI just before Mother's Day. So I wait until mid May before setting anything out. Zinnias are subject to mold from watering on their leaves, especially late in the day or evening. I grow disease resistant zinnias. Ask if they carry those.
if u call Atlantic nursery, they will be able to assist u. they r so helpful! good luck
