Susan, definitely call or email Santa Rosa about adding the Phlox. When I ordered before, I accidentally deleted something from my cart and emailed them asking if they could add it to my order. They not only sent it to me but they gave it to me as a gift! You can't beat that kind of customer service! Now, when I ordered it was summer and they were clearing out plants so you may not get a freebie, but I bet they will add it to your order happily.
