| Family Scientific Name: | Cyperaceae | ||
|---|---|---|---|
| Family Common Name: | sedge family | ||
| Scientific Name: | Carex densa | ||
| Common Synonym: | Carex breviligulata | ||
| Common Name: | dense sage | ||
| Species Code: | CADE8 | ||
| Ecotype: | Seeds from Douglas Co. Oregon | ||
| General Distribution: | Found on the west side of the Cascade Mountain range from central Washington (rare), throughout western Oregon, to northern California. Grows in dense tufts 1.5–3.5 feet tall in seasonally wet areas, such as in vernal pools, on ditchbanks, or wet meadows and marshes from coastal lowlands to western hillsides. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Plug + (container-field grown hybrids) | ||
| Time To Grow: | Weeks | ||
| Target Specifications: | Well-developed crowns, roots and rhizomes filling soil profile in container. | ||
| Propagule Collection: | Moderate. Carex densa should be fairly easy to identify as it has a specific growth habit and generally has relatively large inflorescences (1 to 2¼ inches long by ½ to 1 inch wide) on tall stems (up to waist-height).Seeds per pound: 600,000–700,000 | ||
| Propagule Processing: | Seeds are easily removed from inflorescences using either a combine (during the harvesting process), a stationary combine, or a thresher. An air-screen machine will further separate seed from remaining plant materials and debris. | ||
| Pre-Planting Treatments: | Seeds germinated within 2 weeks when placed in a warm greenhouse (75 degrees). Trials were conducted using different lengths of cold moist stratification: Percent germination with no stratification = 75, 45 days cold-moist stratification= 40, 90 days cold moist stratification= 55 | ||
