Propagation & Germination

Stratification:
Cold/moist stratification required — 30–60 days
Scarification:
Seed coat scarification required before sowing
Germination Time:
14–30 days
Notes:
Scarification with hot water or mechanical abrasion followed by cold stratification improves germination rates significantly.

The above propagation data sourced from Claude AI

Pre-treatment: Scarification using dry tumbling with grit and pea gravel for 5 to 7 days. Soaking/Leaching in a rubber-lined rock tumbler jar with tap water, changing water daily to remove any inhibitors.

Establishment: Seeds collected in Grand Canyon National Park, Arizona. No stratification required. The duration of tumbling for the soaking/leaching process is based on the appearance of the seed and the leach water.
