Propagation
Propagation is easiest by cutting out plugs from established plants. These plugs should have at least one active rhizome, and can grow rapidly under greenhouse care. When establishing stands in the wild, Hierochloe odorata seeds require a period of cold temperatures before they germinate, so planting in the late fall to early spring is best. The seeds have a germination rate of 25-50%. Hierochloe odorata grows best in soil with few competing weeds, loose texture and moistened to the point of surface puddling. Seedlings require constant moisture until they sprout, around 10 to 14 days later.

Ecology
Hierochloe odorata is a marshland species occupying the middle range of habitat between dune and salt marsh ecosystems. The species shows little preference for a soil's nutrient or water content, but is rigidly restricted by pH and salinity. The species is consistently associated with Juncus Balticus in marshlands, and Ammophila breviligulata in dune ecosystems. Hierochloe odorata reaches peak abundance on the edge of competing species ranges. The associated plants are thought to be major inhibitors of Hierochloe odorata growth. Hierochloe odorata is only documented to be browsed by the American Pika (Ochotona princeps) and European Bison. Other Grammivores, such as White-tailed deer, Elk or American Bison may graze on it, but the chemical Coumarin, which creates it's signature vanilla smell, has a bitter taste that deters grazers.
