Hey Wren, just wait until you go in February. (I'll try but I work a lot). The whole garden is incredibly scented with Daphne & Sweet Olive. They had some great deals on the same along with the Camellias. The place where they sell them could easily be missed. It's behind the parking lot in the small greenhouses there. They have their own varieties ("Massee Lane") of Varigated Daphne & Sweet Olive which I purchased and really like them. I believe there were created for more heat tolerance and bloom. The horticulture guys (especially Doug) are there to answer questions too, I drove them crazy trying to find fragrant Camellias.
Take a walk down the paths, some of the bigger greenhouses are back there like the one in my photo. The formal garden is on the back side of the pottery museum, I missed it my first time there.
