Steep slope plants to prevent soil erosion.

Asked April 13, 2018, 10:23 AM EDT

I have a steep slope shoreline bank that faces Northeast. It is 35 in length at a 42degree angle, partially shaded. What can I plant on the slope to eliminate soil erosion, that grows less then 2 1/2 feet in height. I would prefer a flowering plant. Needs an aggressive, deep root system if possible. Best regards.

It will be hard to find a plant that satisfies all your requirements. The limited sunlight greatly reduces the flowering plant possibilities. A ground cover might be best, something like violets or lamium (which do flower). Hosta is a reliable choice. Daylilies might work. If your shoreline borders on a natural area, please be careful with your "aggressive" requirement. Here are a couple of lists from this excellent document:
