Plants are a great solution to erosion, but you do need to choose them carefully. Mr. Mustard sorbaria, which was today’s plant on trial, would actually be a great choice for your environment, so there’s one worth considering. Aronia is another very hardy, very durable option. On the perennial side, you could consider ornamental grasses, liriope (aka lilyturf, though this may not be hardy for you in Alberta), and ferns. In short, you’ll want to look for plants with dense, fibrous root systems rather than those with tap roots. And of course, you’ll want them to be able to easily withstand the dry, sandy soil and light exposure of the area, because any maintenance you need to perform has the potential to worsen the erosion issues.
