I have been getting a lot of great help and finally picked out the main varieties for this back area. I took this picture last night so it is a little dark. I added some drawing to highlight where the three Wax Myrtles are. I will eventually prune to have the leaf canopy over the fence line. The only thing you will see from 6ft and below will be the trunks.

I am adding Japonica camellia to the left side since it is pretty shaded and not much mixed sun. The light colored fence line I want to put a mixture of Sasanqua Camellia and Annabelle hydrangeas. I would love to have an entire hedge of evergreen on the back fence but i want some Annabelle hydrangeas so bad i am going to have to mix it up. I figured I'd put this post in the hydrangea area since yall are more familiar with the sizing of Annabelles.

I was thinking of either 3 camellia and 2 Annabelle or 2 camellia and2-3 Annabelle. I just need help with placement so in the winter i wont have my annabelles cover my camellias and so when the annabelles are dormant, i don't have some odd camellias sitting out there! haha

I have 9 ft from the left tree in the corner to the first wax myrtle. 7 ft in between each wax myrtle and plenty of room on the right side of the right wax myrtle.
