Family Scientific Name: | Rubiaceae | ||
---|---|---|---|
Family Common Name: | Madder | ||
Scientific Name: | Galium boreale L | ||
Common Name: | Northern bedstraw | ||
Species Code: | GABO2 | ||
Ecotype: | Paradise Creek drainage near Pullman, WA. | ||
General Distribution: |
Widespread circumboreal species. In eastern Washington it is usually found on more mesic sites in grasslands of the Palouse Prairie and in open coniferous woods. Mean annual precipitation range is from 20-55 inches (USDA NRCS 2007). Wetland indicator status is FACU (US Fish and Wildlife Service 1988). |
||
Propagation Goal: | plants | ||
Propagation Method: | seed | ||
ProductType: | Container (plug) | ||
Stock Type: | 10 cu. | ||
Time To Grow: | 4 Months | ||
Target Specifications: | Tight root plug in container. | ||
Propagule Collection: | Seed is collected in September when the inflorescence is dry and the seeds are brown in color. Seed can be stripped from the stalks by hand or entire stalks can be cut. Plants hold their seed well, shattering is not generally a problem. Harvested seed is stored in paper bags at room temperature until cleaned. | ||
Propagule Processing: |
Small amounts are rubbed to free the seed, then cleaned with an air column separator. Larger amounts are threshed with a hammermill, then cleaned with air screen equipment. Clean seed is stored in controlled conditions at 40 degrees Fahrenheit and 40% relative humidity. 756,000 seeds/lb (Hassell et al 1996). We determined 725,760 seeds/lb for this ecotype. |
||
Pre-Planting Treatments: |
Germination was equally low for seeds from a Wisconsin source either without pretreatment or after 2 months cold moist stratification (Green & Curtis 1950). Maguire and Overland (1959) found 4 weeks of cold moist stratification resulted in 84% germination, while untreated seed germinated at 64%. For this ecotype, germination without pretreatment is high. Trials conducted at the PMC comparing untreated seed with cold, moist stratified seed showed no benefit from stratification. |
||
Growing Area Preparation/ Annual Practices for Perennial Crops: |
In January seed is sown in the greenhouse in 10 cu. in. Ray Leach Super cell conetainers filled with Sunshine #4 and covered lightly. Head space of ¬ to « inch is maintained in conetainers to allow deep watering. A thin layer of coarse grit is applied to the top of the planting soil to prevent seeds from floating during watering. Conetainers are watered deeply. | ||
Establishment Phase: | Medium is kept moist until germination occurs. Germination usually begins in 10-12 days and is complete in 3 weeks. | ||
Length of Establishment Phase: | 3 weeks | ||
Active Growth Phase: | Plants are watered deeply every other day and fertilized once per week with a complete, water soluble fertilizer containing micro-nutrients | ||
Length of Active Growth Phase: | 2-3 months | ||
Hardening Phase: | Plants are moved to the cold frame in late March or early April, depending on weather conditions. They are watered every other day if the weather is cool, and every day during hot, dry spells. | ||
Length of Hardening Phase: | 2-4 weeks | ||
Other Comments: |
No insect problems have been noted. It may also be possible to propagate this species from pieces of the rhizome or from divisions. |
