Alive Plants to Include in Your Rain Garden

Creating a rain garden requires some effort and careful planning, but it can be an enjoyable process, especially when selecting the plant material. This step is essential in ensuring the success of your rain garden. It is crucial to choose the right plants and place them in the appropriate areas, which will determine whether your garden will thrive or turn into a stagnant, unattractive mess.

A rain garden typically has three planting zones: the edge, the slope, and the base. The edge is the highest part of the garden, where water flows in during heavy rain. The slope is a transitional area between the edge and the base, where the water slows down and infiltrates into the soil. The base is the beautiful lowest part of the garden, where water is held for a short period, allowing plants to absorb it.

When selecting plants for a rain garden, it is essential to consider their moisture tolerance and adaptability to the different planting zones. For instance, beautiful plants that are tolerant of dry conditions should be planted on the edge since this area is usually the driest part of the garden. On the slopes, choose plants that can handle medium moisture with occasional dry conditions. Finally, for the base of the garden, select plants that can thrive in wet conditions and standing water.

By following these guidelines, you can create a thriving mini-ecosystem in your rain garden with native plants that help the environment after every rainstorm while still looking beautiful. Selecting the right plants and placing them in the appropriate areas is crucial in achieving this goal.
