Garden & Ecology Notes
- Wildlife Value:
- bees, butterflies, birds, deer
- Fragrant:
- Yes
- Fire Ecology:
- Requires fire for germination
- Fire Notes:
- Resprouts vigorously from root crown after fire. Seeds exhibit fire-stimulated germination; heat and smoke break seed dormancy. Important post-fire colonizer.
Soil Requirements
- Soil Type:
- well-drained, rocky or sandy soil
- pH:
- 5.5 - 7.5 (slightly acidic to neutral)
- Drainage:
- excellent drainage required
- Moisture:
- dry to moderate
- Notes:
- often found in disturbed sites like post-fire areas
Propagation & Germination
- Stratification:
- Cold/moist stratification required — 90–120 days
- Scarification:
- Seed coat scarification required before sowing
- Germination Time:
- 30–90 days
- Notes:
- Seeds benefit from hot water treatment or fire scarification followed by cold stratification. Smoke treatment may also improve germination.
The above propagation data sourced from Claude AI
Pre-treatment: Seeds: Soak in boiling water for 10 seconds, transfer to cold water, then soak in 1% hydrogen peroxide for 24 hours, rinse, and soak in water for an additional 4 hours. Stratify at 1 to 3 °C for 90 days. Cuttings: Cut into 20-30 cm lengths, treat with 2000 ppm liquid IBA, and place in mist bed with bottom heat.
Establishment: Cuttings taken in late April have the highest rooting percentages. Roots are susceptible to excessive moisture and should be uppotted into a well-drained media and carefully stored over winter. Cuttings produce callus before root initiation. Seedlings require careful irrigation practices, good airflow, and sunlight during growth. They are very susceptible to damping-off disease and must dry down between irrigations.
