What's a fast growing shrub for zone 9?

I live on a corner lot and need some privacy! I don't want to put up fences, I would rather use shrubs. Oh, and my back yard is shady in some areas. I have 3 huge oak trees. Any suggestions??

Kit J is right with the Red Tip suggestion, however they are disease prone. When I lived in that area instead of a fence we had huge Hibiscus bushes. They grew over 5' high and were thick enough to provide excellent privacy.
Reply:Fraser's "red tip" photinia grows pretty and TALL, makes a great privacy hedge. Also variegated pittosporum is a hearty and pretty evergreen shrub that grows to 6 feet wide by 7 feet tall.
Reply:It depends whether you are in Florida or the southwest. If you are in Florida I would try Gardenia because the beautiful smelling blooms. I also like Camelias.


I don't know much about what grows in the southwest.
