Stock Type: stubby containers
Time To Grow: Weeks
Target Specifications: well-developed crowns, roots and rhizomes filling soil profile in container.
Pre-Planting Treatments: Seedling germination appears to be much improved by a cold/moist stratification before placement in a warm growth chamber. 90 days in a cooler set at a constant 38 degrees Fahrenheit increased germination to 62% from the 16% germination seen in seeds sent straight to the growth chamber (set to 70 degrees F during the day and 50 at night).
