Kleim's hardy gardenia
I had a landscape designer draw up plans for my yard and she put some Kleim's gardenias on the plot. I've looked them up and some sites say they are for zones 8 and up and some say 7.
I don't want to go thru a lot of expense and time if they won't thrive here. They would be on a southern exposure yard with full sun until about 3pm. Is this a good idea?
