Family Scientific Name:	APIACEAE
Family Common Name:	Carrot Family
Scientific Name:	Angelica arguta Nutt.
Common Name:	Sharptooth angelica
Species Code:	ANGARG
Ecotype:	Aspen understory,Summit, Glacier National Park, Glacier County, MT1500m elevation
General Distribution:	A. arguta occurs in wet places from the foothills and valleys to mid-montane elevations; from southern B.C. to northern California, east to southwest Alberta and south through Montana, Wyoming and Utah.
Propagation Goal:	plants
Propagation Method:	seed
ProductType:	Container (plug)
Stock Type:	172 ml containers
Time To Grow:	7 Months
Target Specifications:	Height: 7 cm tall, 4to 6 true leaves Caliper: n/a Root System: firm plug in conetainer
Propagule Collection:	Seeds are hand collected in late August/early September when seeds turn brown and are easily stripped from the inflorescence and are kept in paper bags in a well ventilated drying shed during the drying process and prior to cleaning.
Propagule Processing:	Seed longevity is 5 years in sealed containers under 1C. Seed dormancy is classified as morphological-physiological dormancy. Seeds per kilogram: 154,000/kg % Purity: 100% % Germination: 49% to 67%
Pre-Planting Treatments:	Seeds were soaked in 200 mg of activated charcoal per 0.5 liter of water for 24 hours to remove inhibitors from the seed coats. Seeds were placed in 90 day cold, moist stratification. Seeds were placed in fine mesh bags buried in moist peat moss in ventilated containers under refrigeration at 1 to 3C.
Growing Area Preparation/ Annual Practices for Perennial Crops:	Greenhouse facility. Sowing Method: Direct Seeding or Planting Germinants. Seeds are surface sown or lightly covered with medium. Growing medium used is 50% milled sphagnum peat, perlite, and vermiculite with Osmocote 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 occurred after 3 months of cold, moist stratification. Seeds were sown as germinants as the radicle became visible during cold, moist stratification. Non-sprouted seeds germinated under fluctuating temperatures of 16C during the day for 10 hours and 13C during the night for 14 hours. Germination was non-uniform and continued over a 30 day period.
Length of Establishment Phase:	8 weeks
Active Growth Phase:	Root and shoot development occurs rapidly following germination. 4 to 6 true leaves were evident 6 weeks after germination. Plants were fertilized with 20-20-20 liquid NPK at 100 ppm fertilizer during the growing season. Plants were root tight 3 months following germination. Plants will need to be potted into larger containers if held over for more than one season.
Length of Active Growth Phase:	16 weeks
Hardening Phase:	Irrigation is gradually reduced in September and October. Plants are leached with clear water and fertilized with 10-20-20 liquid NPK fertilizer once before winterization.
Length of Hardening Phase:	4 weeks
Harvesting, Storage and Shipping:	Total time To Harvest:10 months Harvest Date: September Storage Conditions: Overwinter in outdoor nursery under insulating foam cover and snow.
Length of Storage:	5 months
Other Comments:	Vegetative Propagation Method: This species is rhizomatous. Divisions can be made of established nursery stock ti increase plant numbers.
