Family Scientific Name:	Asteraceae
Family Common Name:	Sunflower family
Scientific Name:	Townsendia condensata Parry ex Gray
Common Name:	Cushion Townsendia
Species Code:	TOWCON
Ecotype:	Alpine slope, Glacier National Park, MT., 2100 m elevation.
General Distribution:	T. condensata is a short lived perennial which occupies talus and scree slopes at high elevations. It is found from Alberta to northwest Wyoming in scattered locations at high elevations.
Propagation Goal:	plants
Propagation Method:	seed
ProductType:	Container (plug)
Stock Type:	160 ml conetainers
Time To Grow:	6 Months
Target Specifications:	Height: 3 cm, 6 to 10 true leaves<br> Caliper: n/a<br> Root System: firm plug in conetainer.
Propagule Collection:	Seeds are hand collected in late August when achenes turn gray and are easily removed from the disc. Seeds are collected in paper bags and kept in a well ventilated drying shed prior to cleaning.
Propagule Processing:	Seeds are hand cleaned by screening. Seed longevity is estimated at 5 to 7 years at 3 to 5C in sealed containers. Seed dormancy is classified as non deep physiological dormancy. Seeds/Kg: 1,200,000/kg % Purity: 100% % Germination: 10 to 50%
Pre-Planting Treatments:	Dry storage of seeds for 5 months.
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.
Establishment Phase:	Medium is kept slightly moist during germination. Initial germination appeared uniform and occurred following 2 weeks of temperatures at 22C or above during the day.
Length of Establishment Phase:	4 weeks
Active Growth Phase:	Root and shoot development occurs rapidly following germination. Plants were occasionally fertilized with 20-10-20 liquid NPK fertilizer at 100 ppm during the growing season. Do not over water seedlings. Plants were fully root tight 4 months after germination. Plants form flowers the following year.
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 at 200 ppm during the hardening stage.
Length of Hardening Phase:	4 weeks
Harvesting, Storage and Shipping:	Total Time To Harvest: 6 months Harvest Date: September Storage Conditions: Overwinter in outdoor nursery under insulating foam cover and snow.
Length of Storage:	5 months
