alpine areas throughout western
Middle to high elevations (1).
Plant strategy type/successional stage

Collect seeds in late fall, when capsules turn brown and begin to dehisce. Seeds are brown at maturity (1).
120 days cold stratification. Gibrellic acid treatment is recommended for the Pedicularis genus (1).
Seed life (can be stored, short shelf-life, long shelf-life)
Seed longevity is unknown (1).
Clean seeds should be stored in a cool and well-ventilated area.
Soil or medium requirements
Growing media used is 6:1:1 milled spaghnum peat, perlite, and vermiculite with Osmocote controlled release fertilizer (13N:13P2O5:13K2O; 8 to 9 month release rate at 21C) and Micromax fertilizer (12%S, 0.1%B, 0.5%Cu, 12%Fe, 2.5%Mn, 0.05%Mo, 1%Zn) at the rate of 1 gram of Osmocote and 0.20 gram of Micromax per 172 ml conetainer (1).”
Pedicularis groenlandica is a hemiparasite. In order for seedlings to develop a healthy
root system and grow vigorously, a host plant should be introduced into
Care requirements after installed
