Title: Plantings for sides of retention pond in Willits CA
Answered by: Barbara Medford

QUESTION:

I am looking for recommendations for ground cover for the outside of embankments which impound wastewater. This is to improve the aesthetics and deter weeds. The slopes are 1V:2H, so if we can avoid mowing or weed-eating that would be best. Low to moderate water demand would be desirable. Also, this is in full sun. The areas would be bounded by a variety of conditions: native grasses (wetland and upland), AC pavement, concrete, gravel road.

ANSWER:

We believe that you are talking about what we call a retention pond. This is a subject we have dealt with before in various parts of the country. Please read them and follow all the links to more information.

North Carolina -  This answer has many other links to both professional papers and previous answers.

We will take you to our Native Plant Database and give you a list of grasses native to the area of Mendocino County, California. To do this, we will use the Combination Search, entering California, grass or grasslike for Habit, and sun (6 hours or more of sun a day) for Light Requirements. You will then know how to use the database and can make your own selections, possibly selecting small shrubs or even herbs (herbaceous blooming plants) under Habit for variety. You will note on that Combination Search that you can select the Soil Moisture, expected height of plant and even bloom time and color. Each selection you make, of course, will decrease the number of choices you have. It's a great database, but the magic function is out of order. Follow each plant link to our webpage on that plant to learn the propagation, size and growing conditions of that plant.
