Family Scientific Name: | APIACEAE | ||
---|---|---|---|
Family Common Name: | Carrot Family | ||
Scientific Name: | Perideridia gairdneri ( H.&A. ) Math. | ||
Common Synonym: | Carum gairdneri (H.&A.) Gray | ||
Common Name: | Yampah | ||
Species Code: | PERGAI | ||
Ecotype: | Rough Fescue grassland | ||
General Distribution: | P. gairdneri grows in woodlands and dry to wet meadows; from lowlands to mid montane elevations in the mountains. It occurs from southern B.C. to southern California, east to Saskatchewan and South Dakota and Colorado. | ||
Propagation Goal: | plants | ||
Propagation Method: | seed | ||
ProductType: | Container (plug) | ||
Stock Type: | 160 ml conetainers | ||
Time To Grow: | 9 Months | ||
Target Specifications: | Height: 5 cm, 4 to 6 true leaves<br> Caliper: n/a<br> Root System: Small taproot in conetainer. | ||
Propagule Collection: |
Seeds are hand collected in late August when seeds turn dark brown and are easily stripped from the inflorescence. Seeds are collected in paper bags and kept in a well ventilated drying shed prior to cleaning. Collection Locality: Firebrand Pass Trail, Glacier National Park, MT |
||
Propagule Processing: |
Seeds are hand cleaned at the nursery. Seed longevity is up to 5 years in sealed containers at 1 C. Seed dormancy is classified as morphological-physiological dormancy. Seeds per kilogram:250,000/kg. % Purity: 100% % Germination: 65% |
||
Pre-Planting Treatments: |
5 month outdoor cold, moist stratification or a 90 day cold, moist stratification. Seeds are sown in the fall and lightly covered with medium and thouroughly watered prior to winter. Artificially stratified seeds were placed n a 48 hr running water rinse. Seeds were placed in fine mesh bags buried in moist peat moss in a ventilated container in the refrigerator at 1 C. |
||
Growing Area Preparation/ Annual Practices for Perennial Crops: |
Outdoor nursery growing facility. Sowing Method: Direct Seeding. Growing medium used is milled sphagnum peat, perlite, and vermiculite withOsmocote controlled release fertilizer (13N:13P2O5:13K2O; 8 to 9 month release rate at 21C) and Micromax fertilizer (12%S, 0.1%B, 0.5%Cu, 12%Fe, 2.5%Mn, 0.05%Mo, 1%Zn) at the rate of 1 gram of Osmocote and 0.20 gram of Micromax per 172 ml conetainer. |
||
Establishment Phase: | Germination occurs in mid May under fluctuating temperatures of 21 to 24C during the day and 13 to 15C during the night. Medium is kept slightly moist during germination. Initial germination is complete after 2 weeks with seeds stratified outdoors. Seeds sown in the greenhouse following a 90 day cold, moist stratification were germinating at the time of sowing. True leaves were evident 7 days after sowing. | ||
Length of Establishment Phase: | 4 weeks | ||
Active Growth Phase: | Root and shoot development occurs rapidly following germination. 2 to 4 true leaves were evident 6 weeks after germination. Plants were fertilized with 20-20-20 liquid NPK fertilizer during the first half of the growing season. This species develops a short, fleshy taproot. Seedlings must dry down slightly between irrigations. | ||
Length of Active Growth Phase: | 10 weeks | ||
Hardening Phase: | A 10-20-20 NPK liquid fertilizer at 200 ppm is used to promote root development from mid July through September.<br> Hardening Phase: Irrigation is gradually reduced in September and October. Plants are leached with clear water before winterization. | ||
Length of Hardening Phase: | 10 weeks | ||
Harvesting, Storage and Shipping: |
Total Time To Harvest: 9 months Harvest Date: September Storage Conditions: Overwinter in outdoor nursery under insulating foam cover and snow. |
||
Length of Storage: | 5 months | ||
Other Comments: | This is a taprooted species. Conetainers will not completely fill with a root mass and some medium will break away from plug during outplanting. | ||
