odd enough subject to get your attention? Thats basicly what I am attempting to do. I have an old "N" from a cinema sign.Its cleaned and scrubed, and the only way I can keep it is to make it into a small planter. Thats where I come to you guys, The only thing I have ever planted before is hostas, and other shade plants. The area in which I am going to plant in is about 1/2 shade. The N itself is about 4 inches deep, each long side of the N is about 3 feet. I dont mind what I plant actually, it could just be grass. But something that doesnt need much root room. So thats what I come to you for, suggestions on what to plant in it.
