Plant suggestions between a pool & retaining wall.
The space between the pool and retaining wall is 4'. We like the plants to grow up to 5' in the middle. Zone 9/10, full sun, clay soil, Southern California.
I was thinking maybe myrtle/Myrtus communis, where the two pilasters are located at the left and right sides and a flowering shrub in between? I will add a few more pictures.
