| Pre-Planting Treatments: | Our seeds germinated at higher percentages (60% vs. 25%) when they received cold(35F) treatments but seeds also germinated in the warm (75F) treatments. Seedlings in the warm treatments were moldy and seemed less vigorous. A short cold treatment followed by a 50-60F temperatures would probably be the best germination strategy for this species. | ||
