Title: Plants for heavy clay in Sonoma County, California
Answered by: Nan Hampton

QUESTION:

Hi, I live in Northern California, Sonoma County, and would like to transition my front garden into mostly native plants. Trouble is, my soil is clay, yicky, heavy clay, and some of the natives I've tried before haven't survived. Any suggestions on what might like and thrive in clay soil in Sonoma County? Thanks.

ANSWER:

Below are plants that are native to Sonoma County and that will tolerate clay soil.

Artemisia californica (Coastal sagebrush) is an evergreen shrub and will grow in clay.  Here is more information from Las Pilitas Nursery in Escondido and Santa Margarita, CA.

Arctostaphylos glandulosa (Eastwood's manzanita) is an evergreen shrub and will grow in clay.  Here is more information from Las Pilitas Nursery.

Arctostaphylos manzanita (Whiteleaf manzanita) is an evergreen shrub or small tree and will grow in clay.  Here are photos and more information from Las Pilitas Nursery.

Cercis orbiculata [syn. = C. occidentalis] (California redbud) is a flowering shrub or small tree.  Here is ore information from Las Pilitas Nursery.
