Thank you for the information!
They are about 4' high right now and are so intertwined you can not even differentiate between one bush to the other.
I would really like to use 2 different kinds to change it up a bit. I live in SC, very hot and humid during the summer months.
The sun comes from the south at the back of my house, but the front gets direct sunlight the majority of the day, just not early morning sun.
I'm going to try and send a pic so you can see what I'm talking about.
Again, thanks so much!
