Drought resistant, tall plants for a narrow side yard?
I have a really narrow (5 ft wide, 30 ft long) side yard currently does not have any plants. My living room and kitchen window directly looks into this side yard, where we can only see our old fence and neighbor's wall, which is not exciting at all for sure :)
So my plan is to plant some easy maintaining, tall (3 to 6 ft) plants that's also drought resistant (maybe watering every other week), since I don't have sprinklers there. Also since the yard is so narrow, I'd like the plants to be not too big in thickness.
Any suggestion would be greatly appreciated!
