Here in the above image we can see the prominent lines in the area drawn over the landscape.
I did start with your sketch, and took it forward from there. In the images you will see Drift Roses, May Night Salvia, Skip Laurels, Green Mountain Boxwoods, and Osmanthus False Holly.
The pinkish colorred plants with flowers are the Coral Drift Roses, and the purple perennials are May Night Salvia.
The taller green bushes for privacy are Skip Laurels and the small cone shaped bushes are Green Mountain Boxwoods.
The walkway is represented as gravel with stepping stones, and the patio is represented as gray pavers.
Here in the images I am representing the concrete pad as cleaned up and grayish with a gray paver.
The plants along the wall and around the Jacuzzi are the Osmanthus False Holly.
Edging along the fence.

Take a look over these images and lets talk by phone, if you guys don’t need any changes I can start on the pricing for the work. Thank you and have an awesome day.
