Soil Requirements
- Soil Type:
- rich, well-drained loamy soil
- pH:
- 6.0 - 7.5 (slightly acidic to neutral)
- Drainage:
- excellent drainage required
- Moisture:
- dry to moderate

Propagation & Germination
- Stratification:
- Cold/moist stratification required — 60–90 days
- Germination Time:
- 14–42 days
- Notes:
- Seeds may have double dormancy; some sources suggest warm stratification followed by cold improves germination rates.
The above propagation data sourced from Claude AI
Pre-treatment: Seed was placed in ziplock bags with damp coarsely torn sphagnum moss and placed in 40C cooler for 5 months. Alternatively, seed can be sown right away after drying.
Establishment: Seed flat must be kept sheltered from rodents as they will disturb and eat seeds. Seedling roots may become entangled in sphagnum moss fibers and roots of seedlings may perforate wings of adjacent seeds if seeds are stuck together when initially sown in the trays.

ORGHPS Germination Guide: Sow @ 4C for 3 months, then place @ 20C for 3 months.
