We have an area that is roughly 14 inches wide by about 50 feet long. On one side is a retaining wall and alley on the other is a sidewalk and then the house. The soil would not be considered well draining, but does not pool water. It gets morning and early afternoon sun.
We are looking for a plant that will grow between 3 and 5 feet tall or can be trimmed into shape. It has to be sturdy so it does not obstruct the alley. also would like it to have roots what will not destroy the sidewalk or the retaining wall.
Do you have any suggestions?
