Family Scientific Name:	Asteraceae
Family Common Name:	Sunflower Family
Scientific Name:	Anaphalis margaritacea (L.) Benth. & Hook. f.
Common Name:	Western pearly everlasting
Species Code:	ANAMAR
Ecotype:	Ecotype from Old Faithful Main Shop Area of Yellowstone National Park
Propagation Goal:	plants
Propagation Method:	seed
ProductType:	Container (plug)
Stock Type:	10-cubic-inch conetainers.
Time To Grow:	0
Propagule Processing:	Process dry seedheads in hammermill using #5 (0.08 in diameter holes) screen. Large debris can be removed from processed material using hand sieves. Run remaining material over fanning mill with medium wind to remove chaff.
Pre-Planting Treatments:	A 6-week cold moist stratification at 34 to 37øF resulted in good germination of 1-y-old seeds (>50%), although trials to determine optimum dormancy breaking treatment were not conducted. Sow seeds directly onto a peat-lite mix and cold chill, or stratify seeds in a 50:50 sand:peat moss mix in a ventilated ziplock bag. Moisten seed and media and allow to imbibe water overnight before placing in cooler. Ten-cubic-inch conetainers are adequate for 1-0 production.
Growing Area Preparation/ Annual Practices for Perennial Crops:	For container production, use a well-drained peat-lite mix with baseline nutrition.
Establishment Phase:	This species grows well in a greenhouse at 75 to 80øF days and 60 to 65øF nights on 14- to 16-hour photoperiods. Keep media fairly moist. Fertigate weekly with 9-45-15 at 150 to 250 ppm for the first 4 to 6 weeks then use 20-10-20 at 150 to 200 ppm each week for the remainder of the growing season.
Hardening Phase:	Move containerized material (at least 2 months old) started in the greenhouse that winter to an outdoor hoophouse in late spring/early summer (i.e. "finish" the plants in the hoophouse). Our hoophouse is ventilated but not cooled, and the containers are usually exposed to full sunlight for 2 to 4 weeks early in the season. The hoophouse is then covered with a 50% shade cloth until temperatures cool in the fall. Another option is to finish container plants in the greenhouse and then move them to the shadehouse in late summer, allowing 30 to 60 days of hardening prior to winter. The shade is usually removed in late summer/early fall and replaced with clear plastic. The plants harden-off gradually in the hoophouse prior to winter. Bridger is characterized by a high number of solar days that keeps the environment inside the hoophouse relatively mild until winter. In the case of premature and severely cold weather, a small propane heater is used at keep temperatures above freezing.
Length of Hardening Phase:	As a standard practice, we allow a minimum of 30 days of hardening off prior to killing frost, 60 days is preferred.
Harvesting, Storage and Shipping:	No experience, this species was delivered as actively growing stock in early summer of the first growing season. We generally prefer to hold over all container plants for one winter prior to outplanting. Length of Storage: No experience.
Other Comments:	Easy togrow from seeds.
