I did think of bamboo but it can then sprout up over into their property line ensuring that all hell would break loose. I think i'll go with the Maiden grass, the bottom half of it is sharp but the top half has long whispy feather like pink blooms I guess you'd call them
Then maybe do like a zebra type grass in the front
I think we will eventually build some long planting boxes with fairly solid bases and then put some maiden grass in them and place them on top of the sand mound, seeing as we can't plant ON the stupid thing!
Wow that is nice! And the reason I recommended it is because I have it in my yard and have never seen or heard the neighbors on the other side of the bamboo line LOL
