|Family Scientific Name:
|Family Common Name:
||Koeleria macrantha (Ledeb.) Schultes
||Koeleria cristata Pers.
||Festuca idahoensis grassland, Rising Sun, Glacier National Park, Glacier Co., MT., 1585m elevation.
||K. macrantha occurs in sagebrush deserts, prairies, open forests to open ridges in the subalpine zone on rocky or well drained soils. It ranges from B.C. to northern Mexico, east to Ontario and Maine, throughout the western states south to Texas and Louisiana. It is also found in Delaware.
||160 ml conetainers
|Time To Grow:
||Stock Type: Container seedling
Height: 10 to 20 true leaves, 10 cm
Root System: firm plug in conetainer.
||Seeds are collected in mid to late August when florets turn from papery and tan and seeds are easily shaken out of florets. Seeds are collected by cutting the entire inflorescence just prior to shattering. Seeds are spread on an opened tarp in the drying shed.
||Seeds are cleaned using a de-huller at NRCS.
Seed Storage is estimated at 3 to 5 years at 3 to 5 C in sealed containers.
Seed dormancy is classified as non dormant.
% Purity: 100%
% Germination: 40%
||None. Germination is reported to be higher in the presence of light.
|Growing Area Preparation/
Annual Practices for Perennial Crops:
Greenhouse and Outdoor Nursery growing facility.
Sowing Method: Direct Seeding. Seeds should be surface sown.
Growing medium used is 6:1:1 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.
Greenhouse temperatures are maintained at 21 to 25C during the day and 16 to 18C at night. Seedlings are hand watered and remain in greenhouse until mid May. Seedlings are then moved to outdoor nursery for the remainder of the growing season.
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.
||Medium is kept slightly moist during germination.
|Length of Establishment Phase:
|Active Growth Phase:
||Root and shoot development occurs rapidly following germination. Seedlings develop 4 to 6 true leaves 3 weeks after germination. Seedlings were fertilized with 20-20-20 liquid NPK at 100 ppm during the growing season.
|Length of Active Growth Phase:
||Irrigation is gradually reduced in September and October. Plants are leached with clear water once before winterization.
|Length of Hardening Phase:
|Harvesting, Storage and Shipping:
||Total Time To Harvest: 12 weeks
Storage Conditions: Overwinter in outdoor nursery under insulating foam cover and snow.
|Length of Storage:
|Outplanting performance on typical sites:
||Outplanting Site: Saint Mary, Glacier National Park, MT.
Outplanting Date: September
