Ferns grow abundantly in Vancouver and BC - helping to stabilize slopes and prevent erosionSo you've built a retaining wall (or several) on your property. The next step in your landscaping adventure is to get planting on those new slopes that your retaining wall is holding up. Whether you've got one large slope, or several tiered areas, you need some greenery in there to call the project finished.
Your favourite plants, flowers and shrubs are a great start. But we also recommend that you add some plants that are known for minimizing soil erosion into the mix. These plants spread quickly (both above and below ground). Your rock solid wall will get an extra boost from a slope peppered with these erosion controllers.
Erosion preventing perennials
This list of perennials that thrives in Vancouver and the West Coast is sure to get you going...
- Shield Fern (Dryopteris filix-mas) - You see ferns all over the forest floor and on many a slope for good reason. They are natural erosion preventers and soil creators.
- Bugleweed(Ajuga reptans) - Mahogany leaves and spiky blue flowers add an eye pleasing punch to your landscape.
- Pussy slope(Antennaria) - This hardy plant is perfect for dry areas and can even withstand foot traffic. This silvery-grey foliage will call even the most inhospitable slope home.
- Snow in Summer(Cerastium tomentosum) - You guessed it - this plant is named for snowy white flowers and is know for its awesome creeping ability.
- Cliff Green(Paxistima canbyi) - This evergreen perennial is also quite the spreader and sports while flowers in the summer.
- Fleece Flower(Persicaria affinis) - If you love brightly coloured flowers, use this mat-forming bloom to add some colour to your slope.
- Ribbon Grass(Phalaris arundinacea) - This grass with lovely white striped blades is an aggressive one and will have your slope in shape in no time.
Try planting these perennials to make your retaining wall look right at home on your property and add some additional slope stabilizing power. Gotta love the kill two birds with one stone principle! If you're looking to get some landscaping done after Dig has finished your retaining wall, let us know. We'd be happy to recommend one of our local, Vancouver landscaping crews.
In the next post, we'll look at some trees and shrubs that can also help with erosion control. Stay tuned and happy summer!
