With a raised bed garden, try growing fruits or vegetables. Vegetables such as tomatoes or cucumbers or peppers would make a great addition.
Growing in a cinder block planter wall
Unlike growing in a raised cinder block garden, with a planter wall space is something that must be considered. The relatively small planter means that you must grow something that will be able to live within the block. Succulents, grasses or herbs such as oregano or basil would be good candidates for cinder block wall planters. Small flowers are a great way to add a pop of color.
