Family Scientific Name: Cyperaceae
Family Common Name: Sedge family
Scientific Name: Schoenoplectus tabernaemontani (K.C. Gmel.) Palla
Common Synonym: Scirpus validus Vahl
Common Name: Softstem Bulrush
Ecotype: Freshwater marsh near Knik Arm, Matanuska Valley, Alaska
General Distribution: Cosmopolitan. In Alaska, south of the central Brooks Range to northern Cook Inlet, then south and east to SE Alaska and the Yukon Territory.
Propagation Goal: plants
Propagation Method: seed
ProductType: Container (plug)
Time To Grow: 0
Target Specifications: Containerized plants with multiple leaves and well-developed roots ready for direct field transplanting.
Propagule Processing: Westrup LA-H breaks up seed heads and separates seed. Air separation cleans out the trash.Previously, seed was dried and stored frozen. Currently, seed is kept moist and refrigerated until sown.
Pre-Planting Treatments: Past treatments included Fall-sowing in flats with Cornell wetland mix. After saturation with water, they are exposed to winter temperatures until Spring when they are moved to the greenhouse. Germination was approximately 25% and spotty.
Presently, chilled moist seed is sown in flats on the surface of the medium. It is then overwintered as above for ~5 months. In Spring, they are moved to the greenhouse. This protocol will be updated when new results become available.
Hardening Phase: Flats with young plants are moved from the greenhouse to an outdoor sheltered area in late June. Successful outplantings have been done in late July and August.
Other Comments: Present experimentation involves two factors:
1) Keeping harvested seed moist until sown.
2) Sowing on the surface to allow exposure to light.
