Coastal sage scrub permaculture🌻🐝

Problem statement

I live in the coastal sage scrub plant community. I’d like the plants growing around my home to reflect this community and/or produce food.

The permaculture discipline provides handy phrases like guild (recreations of plant communities found in nature) and companion plants (symbiotic or mutually supportive), and concepts like a seven-layer garden and soil building.

I’ve found Gaia’s Garden by Toby Hemenway a concise introduction.

Paul Stamets, a hero, is a fan of permaculture and proposes a Stametsian Model with an eighth layer for fungi.

Las Pilitas Nursary is a rich source of native plant and permaculture information. CNPS also enables us to search shade plants by zipcode. Oaktown nursery is one of my favorite sources of native plants.

So, the challenge is: build a California coastal sage scrub guild.

Solution

Here are the plants I’ve tried:

Latin name Common name Layer Health* Sun* Water* Notes
Achillea millefolium californica California yarrow Herb 4 2 & 5 1 Suspect more sun needed, but one in the front yard in shade is fuller.
Allium triquetrum Three-cornered leek Herb 5 1 1 Self-propagating. Curious to try a native Allium like Allium unifolium
Agapanthus praecox orientalis Lilly of the Nile Shrub 5 1 1 Prolific in the front yard in shade
Aquilegia eximia Serpentine columbine Shrub 4 3 2 The columbine’s health steadily declined after planting, dropping leaves and never flowering. Transplanted to pot with potting soil and more sun and care and it rebounded. Recently transplanted back.
Armeria maritima Sea thrift Ground 🤞 4 2 Planted Spring 18
Artemisia douglasiana California Mugwort Herb 4 2 1 Died back completely in summer, but resprouted and grew vigorously after Spring rain
Asarum caudatum Western wild ginger Root 3 1 2 Leaves look good, but growth is slow and it hasn’t flowered. I suspect it needs more water
Brugmansia arborea Trumpet flower Low tree 4 2 1 Flowering and leaves look good. Suspect more sun needed
Callistemon rigidus Bottlebrush tree Low tree 5 3 1 Flowers profusely year-round
Citrus tangerina Tangerine tree Low tree 2 3 1 The tree produces inedible fruit and its leaves are chlorotic and sparse :( I suspect it used to get insufficient sun. An arborist mentioned citrus trees are “hungry”, so this one may just need fertilizer. There’s a lemon tree in the front yard that looks great, for comparison
Camellia japonica Camelia Low tree 5 2 1 Two camellias on the property outside dripline. One in good health, but one suddenly whithered. Suspecting gophers although they left the other alone.
Chlorogalum pomeridianum Soap plant Herb 🤞 3 1 Spring 18. Inspired by native uses.
Claytonia sibirica Candy flower Herb 5 1 2 Leaves and growth look great. Flowering. Neighboring ginger
Collinsia heterophylla Chinese houses Shrub 🤞 2 1 Planted Spring 18. Flowering!
