Garden & Ecology Notes
- Wildlife Value:
- birds, butterflies, native bees, beneficial insects
- 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 coastal scrub fire ecology, providing quick post-fire erosion control.
Soil Requirements
- Soil Type:
- sandy, well-drained, nutrient-poor soil
- pH:
- 5.5 - 7.5 (slightly acidic to neutral)
- Drainage:
- excellent drainage required
- Moisture:
- dry to moderate
- Notes:
- thrives in coastal scrub and chaparral environments
Propagation & Germination
- Stratification:
- None required
- Germination Time:
- 14–30 days
- Notes:
- Seeds germinate readily without treatment. Light may enhance germination. Vegetative propagation via cuttings is more reliable.
The above propagation data sourced from Claude AI
Pre-treatment: Dip cut end in 1:20 solution of Wood's brand rooting hormone recommended for herbaceous cuttings. Alternatively, cuttings can be dipped in a mild bleach solution for 30 seconds and treated with Hormex (3000 ppm IBA) rooting powder.
Establishment: There is a variation in the pre-treatment and establishment protocols between the three protocols. The source of propagation can also be from seeds as per Protocol 2, but cuttings were preferred due to higher germination rates. The collection of cuttings and seeds also varies with the time of the year.
