For local information such as you are requiring, you might want to visit some of the local garden centers. I do not mean the big box stores, which are absolutely worthless when it comes to relating regional information. Find the locally owned places and talk to the staff.

I have purchased camellias at the Evergreen Nursery on Black Mountain Rd. (and at a Costco road show also...) My planting conditions are simliar to yours, although one site I was convinced would get too much sun. They are thriving!!

Good Luck.

They're pretty easy. Walter Anderson's has a nice selection. They have a nursery in Poway and one in Pt. Loma. They won't sell you anything that won't do well in your area and they are very knowledgeable.

There is a guy at the Walter Andersen's Poway store who LOVE's camellias. He orders all different varieties for SD. I am sorry I forgot his name. He would be happy to guide you to the right plant
