| Family Scientific Name: | Cyperaceae | ||
|---|---|---|---|
| Family Common Name: | sedge family | ||
| Scientific Name: | Carex pachystachya | ||
| Common Name: | chamisso sedge | ||
| Species Code: | CAPA14 | ||
| Ecotype: | high elevation and low elevation populations | ||
| General Distribution: | Widespread in mesic transition zones between wet and drier habitats, in moist meadows, wet prairie, marsh edges, forest edges, and roadsides; common at low elevations but extending to high elevations. Found from Alaska to California and west to Colorado. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Time To Grow: | Weeks | ||
| Target Specifications: | Well-developed crowns, roots and rhizomes filling soil profile in container. | ||
| Propagule Collection: | Moderate. This species is usually found in large patches, but heads must be collected individually because they grow intermixed with other species. Carex pachystachya resembles other native sedges, but cannot be easily confused with any non-native sedges. Seeds per pound: 750,000–800,000 | ||
| Propagule Processing: | Seeds should be dislodged from stems by threshing or stationary combining. Air-screen machines are then used to remove chaff, debris, and empty seeds. | ||
| Pre-Planting Treatments: | Seeds are usually dormant and need six or more weeks cold-moist stratification before germinating when temperatures increase in late spring. . To overcome seed dormancy, sow seeds in containers and place in a cooler (45°F or lower) for at least six weeks. Alternately, containers can be placed outside in early September through December for six weeks. After a cold period, move containers to a greenhouse set between 70 and 80°F in late December. Seeds should germinate within 2–4 weeks if they receive heat, light, and water. | ||
