Plants that draw water away from the foundation of a building can be beneficial in preventing water damage and maintaining the structural integrity of the foundation. Here are some native perennials that can help with this:
1. Coneflower (Echinacea): Coneflowers have deep and extensive root systems that can absorb a significant amount of water from the soil. They are also drought-tolerant, making them ideal for areas with inconsistent rainfall. Additionally, their vibrant flowers attract pollinators, adding beauty to your landscape.
2. Cinnamon Fern (Osmunda cinnamomea): Cinnamon ferns thrive in moist soil and can help drain excess water away from the foundation. They are known for their unique cinnamon-colored fertile fronds, which add an interesting texture to the garden.
3. Phlox (Phlox spp.): Phlox varieties, such as woodland phlox and garden phlox, have spreading root systems that can efficiently absorb water. They also produce lovely clusters of flowers in various colors, adding visual appeal to your garden.
4. Aster (Aster spp.): Asters are hardy perennials with deep roots that can draw water away from the foundation. They bloom in late summer and fall, providing a burst of color when many other plants have finished flowering.
5. Black-eyed Susan (Rudbeckia hirta): Black-eyed Susans have deep taproots that can access water deep within the soil. They are also drought-tolerant and produce iconic yellow flowers with dark centers, attracting butterflies and bees to your garden.
6. Columbine (Aquilegia spp.): Columbines have long taproots that can reach water sources deep in the soil. These elegant flowers come in a variety of colors and attract hummingbirds and butterflies.
7. Lobelia (Lobelia spp.): Lobelias, particularly the cardinal flower (Lobelia cardinalis), thrive in wet soil conditions. Their vibrant red flowers are a magnet for hummingbirds, and their root systems can help drain excess moisture away from the foundation.
8. Native Grasses: Switch grass (Panicum virgatum) and Indian grass (Sorghastrum nutans) are two native grasses with deep root systems that can effectively draw water away from the foundation. These grasses also provide habitat for birds and other wildlife.
It’s important to note that while these plants can help with water drainage, they should be planted at an appropriate distance from the foundation to avoid any potential damage. Additionally, ensure that the soil around the foundation slopes away from the building to facilitate proper water runoff.
In my experience, incorporating a combination of these native perennials into a garden or landscaping design can not only help draw water away from the foundation but also create a beautiful and sustainable outdoor space. I have personally seen the positive impact of these plants in diverting water and preventing water damage to buildings.
