The house we bought has a back deck that anyone can see from blocks away and the way it is curved puts it about 8ft from a sidewalk. The deck sits approximately 2.5ft off the ground. We are looking for a tall grass that will mostly grow up instead of out given the constrain of the sidewalk, and will reach somewhere between 7-10ft in height.I keep thinking I have found something, but it's hard to tell when you find heights for the same grass ranging from 7 feet on one site to 3 feet on another (Well which is it already!? grrrrrr!!!!) Does anyone have any suggestions? Suggestions from grasses you have dealt with or personally seen would be the most helpful.
I didn't have a real picture so I just pulled one from google maps. Ignore all the weeds and the tree. They are not there any longer. The weeds because ick, and the tree because it was trying to break into the basement and we had to chop it down in order to get insurance on the house.
