The above propagation data sourced from Claude AI

Pre-treatment: Seeds were placed on a moist germination towel, rolled into ragdolls, secured with a small rubber band, and placed into sealed plastic snack bags. No scarification required.

Establishment: Unlike Trifolium stoloniferum, running glade clover does not appear to require scarification. Seeds were ordered from USDA GRIN.
