Germination of Alaska-Cedar Seed

Seeds of Alaska-cedar (Chamaecyparis nootkatensis D. Don) were tested for germination following combinations of warm and cold stratification. For nursery sowing, good germination can be achieved using 60 days of warm stratification followed by 90 days of cold stratification. Extending stratification periods beyond these times may result in seed loss from seed germination during stratification and from seed molds. Unstratified seed sown in greenhouses in late summer will germinate well the following spring if greenhouse temperatures are lowered during fall and winter to meet cold stratification requirements.
