Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Please forgive us, but Mr. Smarty Plants has been overwhelmed by a flood of mail and must take a break for awhile to catch up. We hope to be accepting new questions again soon. Thank you!

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
