Garden & Ecology Notes
- Wildlife Value:
- birds, small mammals, bees, livestock
- Deer Resistant:
- Yes
- Salt Tolerant:
- Yes
- Fragrant:
- Yes
- Fire Ecology:
- Fire adapted — tolerates or benefits from fire
- Fire Notes:
- Resprouts vigorously from the root crown following fire or top-kill. Deep taproot provides resilience to drought and disturbance.
Soil Requirements
- Soil Type:
- sandy, well-drained, nutrient-poor soil
- pH:
- 6.0 - 8.0 (neutral to slightly alkaline)
- Drainage:
- excellent drainage required
- Moisture:
- dry to moderate
- Notes:
- native to arid desert regions
Propagation & Germination
- Stratification:
- None required
- Scarification:
- Seed coat scarification required before sowing
- Germination Time:
- 7–30 days
- Notes:
- Hard seed coat requires scarification (mechanical or hot water treatment). Seeds germinate readily after scarification without stratification.
The above propagation data sourced from Claude AI
Pre-treatment: Seeds are hand scarified by clipping and directly sown in open flats using a growing medium of 2 parts sand, 1 part mulch and 2 parts perlite.
Establishment: Seeds are hand collected in December when pods have matured and begin to split open. The plant is common in washes below 5,000 ft elevation from northwestern Mexico to California east to Texas.
