Coastal sage scrub permaculture🌻🐝

Problem statement

I live in the Burlingame "Terrace", which is 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 and Bay Natives are 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 5 3 & 5 1 Loves the sun. No water required. Spreading and flowering, but more slowly in part-shade.
Allium triquetrum Three-cornered leek Herb 5 1 1 Pre-existing. Non-native. Self-propagating. Curious to try a native Allium like Allium unifolium
Agapanthus praecox orientalis Lilly of the Nile Shrub 5 1 1 Pre-existing. Non-native. 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.
Arctostaphylos densiflora "Sentinel" Manzanita Sub-canopy 🤞 4 1 Yerba Buena nursery has a good description of A. densiflora "Sentinel". Planted summer 2018.
Armeria maritima Sea thrift Ground 🤞 4 2 Planted Spring 18. Visibly wilts without regular water.
Artemisia douglasiana California Mugwort Herb 4 2 1 Died back completely last summer, but resprouted and grew vigorously after spring rain, and is remaining green this summer
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 Sub-canopy 4 2 1 Flowering and leaves look good. Suspect more sun needed

Citrus tangerina Tangerine tree Sub-canopy 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 Sub-canopy 5 2 1 Pre-existing. Non-native. Two camellias on the property outside dripline. One in good health, but one suddenly whithered. Suspecting gophers although they left the other alone.
