The above propagation data sourced from Claude AI

Pre-treatment: For seeds: Cold moist stratification for 56 days. For cuttings: Hardwood tip cuttings are collected before leaf buds break dormancy, softwood cuttings are collected when stems are fully leafed. Cuttings are 3 to 5 cm in length and 4 mm in caliper and are treated with 1000 ppm IBA.

Establishment: S. reticulata is found in subalpine and alpine zones; from Alaska to Newfoundland and south to New Mexico, Utah and California. S. reticulata ssp. nivalis occurs from southern B.C. and Alberta to California, Utah and south through the Rocky Mountains to New Mexico at high elevations in meadows, talus and scree slopes.
