Family Scientific Name: Cyperaceae
Family Common Name: Sedge family
Scientific Name: Carex jonesii L. Bailey
Common Name: Jones' sedge
Species Code: CAJO
Ecotype: Seeds were collected from Lassen National Park.
Propagation Goal: plants
Propagation Method: seed
ProductType: Plug + (container-field grown hybrids)
Time To Grow: 4 Weeks
Target Specifications: Good looking plug with roots that tightly fill the cone-tainer.
Propagule Collection: Seeds were hand stripped from plants when mature.
Propagule Processing: Seeds were cleaned using a small air screen machine.
Pre-Planting Treatments: Germination trials were performed using different lengths of cold-moist stratification. No strat= 56% germination.
45 days of strat= 62% germination. 90 days strat= 48% germination.
Growing Area Preparation/
Annual Practices for Perennial Crops:		 Seeds were sown into cone-tainers filled with Sunshine#1 (a soil-less,peat-based media)amended with micro-nutrients (Micromax) and a slow-release fertilizer (Osmocote 14-14-14). Flats of cone-tainers germinated in warm temperatures around 80 degrees F.
Other Comments: Highest germination occurs in warm (80 degrees) temperatures.
