Q. Who is Mr. Smarty Plants?

Topic: Erosion Control
Title: Groundcover for erosion control
Answered by: Nan Hampton

QUESTION:

I live in southern california. What is the best groundcover to plant on a slope to prevent erosion?

ANSWER:

Grasses, with their dense fibrous root systems, are one of the best plants to use for erosion control.  Here are a few suggested grasses for southern California:

Achnatherum hymenoides (Indian ricegrass)

Festuca californica (California fescue)

Koeleria macrantha (prairie Junegrass)

Melica imperfecta (smallflower melicgrass)

Sporobolus airoides (alkali sacaton) and more information

Here are some low-growing shrubs that could be used as groundcovers.  These could be used along with the grasses or instead of the grasses.  Their height is generally 1 to 3 ft.

Symphoricarpos mollis (creeping snowberry) with more information.  This is low-growing shrub that is generally less than 2 feet tall.

Encelia farinosa (brittlebush) with more photos and information

Eriogonum fasciculatum (Eastern Mojave buckwheat) with more information

Mahonia repens (creeping barberry) with more information
