For the planting, porous concrete block is demanded ability to passing water and air through void of block. In this paper, material used for porous concrete block is cement, rice straw ash, and coarse aggregate(5-10, 10-20, 5-20mm). Planting block size is 23*23*4cm and kinds of planting are Tall fescue, Lespedeza cyrtobotrya and Lespedeza cuneata. The results measured for three months show that possible planting of various kinds for porous concrete block.
