The first thing that comes to your mind when one mentions rain is the lovely droplets falling onto the ground and quenching the thirst of the parched earth. In fact, a rain garden does as a matter of fact, do something like that.
For instance, you can have dark soil and a flowering bush in one piece, and sand and a cactus variety in another. This way the garden will look nice when there are no plants too, because of the different colored soils and also after the plants grow and bear flowers!
Around this fountain or cauldron, you can either simply plant lawn grass or plant one single variety of a flowering bush or shrub. The contrast will look very pretty and inviting and render a cool environment to the visitors.
Use appropriate soil that is capable of draining the water well. You can test the draining ability of the soil in the area by digging a hole and filling it with water to check how much time it takes to drain. Follow these steps and have a gorgeous garden in your front or backyard and save precious water!
