Backyard Privacy - need some creative help
My husband and I recently purchase our home and now we are in desperate need of some backyard privacy. The picture was taken from my patio looking into my neighbors yard and house. The two bushes that are stand are rose of sharon and I would like to at least keep the largest one (on the left). I thought about planting some tall ornamental grass along with a mixture of other things but really I am at a loss. I don't know where to begin or what to put in the ground. I would be so grateful for some suggestions.
