Family Scientific Name:	Juncaceae
Family Common Name:	Rush family
Scientific Name:	Luzula glabrata Hamet-Ahti hitchcockii (H„met-Ahti) Dorn
Common Synonym:	Luzula hitchcockii Hamet-Ahti
Common Name:	Hitchcock's smooth woodrush
Species Code:	LUZHIT
Ecotype:	Subalpine meadows, Logan Pass, 2032m elev.
General Distribution:	L. glabrata var. hitchcockii occurs from southern B.C. to Oregon, and from southwest Alberta, Idaho, Montana, and northern Wyoming; in montane forests to subalpine and alpine meadows and slopes.
Propagation Goal:	plants
Propagation Method:	seed
ProductType:	Container (plug)
Stock Type:	160 ml conetainers
Time To Grow:	1 Years
Target Specifications:	Stock Type: Container seedling<br> Height: 4 to 6 true leaves; 5 to 6 cm<br> Caliper: n/a<br> Root System: Firm plug in containers.
Propagule Collection:	Fruits are reddish-brown capsules containing three seeds Seeds are collected in September when capsules begin to split open revealing shiny black seeds. Seeds are collected using scissors and paper bags.
Propagule Processing:	Seeds are cleaned with a hammermill and thresher. Seeds are stored at 0C and low humidity in sealed containers. Seed longevity is unknown. Seed dormancy is classified as physiological dormancy. Seeds/Kg: 1,950,700/kg % Purity: 100% % Germination: N/A
Pre-Planting Treatments:	Outdoor nursery seed subjected to 5 month outdoor cold, moist stratification. Mechanical or hot water scarification or repeated freeze thaw cycles of stratified seeds may aid in breaking physical dormancy and increasing germination percentages.
Growing Area Preparation/ Annual Practices for Perennial Crops:	Outdoor nursery growing facility. Sowing Method: Direct Seeding. Seeds are lightly covered with medium. Growing medium used is 6:1:1 milled spaghnum 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 conetainer. Conetainers are filled and sown in late fall and irrigated thoroughly prior to winter stratification.
Establishment Phase:	Seedlings germinate in spring under fluctuating outdoor temperatures and are grown under full sun exposure. Seedlings are irrigated with Rainbird automatic irrigation system in early morning until containers are thoroughly leached. Average growing season of nursery is from late April after snowmelt until October 15th. Media is kept moist during germination. Shoot and root development occur slowly following germination.
Length of Establishment Phase:	8 weeks
Active Growth Phase:	Root development of this species occurs at a moderate rate during the growing season. This species has a loosely caespitose root system. Plants grown in conetainers do not fill; shallow square pots are more appropriate.
Length of Active Growth Phase:	12 weeks
Hardening Phase:	Plants are fertilized with 10-20-20 liquid NPK at 200 ppm during August and September. Irrigation is gradually reduced in September and October. Plants were given one final irrigation prior to winterization.
Length of Hardening Phase:	4 weeks
Harvesting, Storage and Shipping:	Total Time to Harvest: 1 year Harvest Date: July Storage Conditions: Overwinter in outdoor nursery under insulating foam cover and snow.
Length of Storage:	5 months
