Garden & Ecology Notes
- Wildlife Value:
- butterflies, native bees, birds
- Deer Resistant:
- Yes
- Salt Tolerant:
- Yes
- Fragrant:
- 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

- 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.
