butterflies, native bees, birds
Deer Resistant:
Yes
Salt Tolerant:
Yes

Fire Ecology:
Fire adapted — tolerates or benefits from fire
Fire Notes:
Resprouts vigorously from root crown after fire. Important component of fire-adapted coastal sage scrub communities with typical fire return intervals of 30-65 years.

Soil Requirements

Soil Type:
sandy, well-drained, nutrient-poor soil
pH:
6.0 - 8.0 (slightly acidic to neutral)
Drainage:
excellent drainage required
Moisture:
dry to moderate
Notes:
Thrives in coastal sage scrub environments

Propagation & Germination

Stratification:
None required
Germination Time:
14–30 days
Notes:
Seeds germinate readily with adequate moisture and warmth. Light may enhance germination. Can be propagated more easily from cuttings.

The above propagation data sourced from Claude AI

Pre-treatment: Seeds germinate at 23 C in light. Seed germination is stimulated by the presence of charred wood or aqueous extracts of it. 5% increase in germination as compared to control.

Establishment: Seeds are collected between October 1st and January 1st. Mature inflorescences are brown. Seed is light to dark brown at maturity. It is important to pull achenes out of seed head at time of collection to check for maturity. Seeds should not be green. A. californica is found on dry slopes and fans, below 900 meters elevation, in coastal scrub and strand communities; from Marin and Napa counties south to Lower California.
