Family Scientific Name:	Polygonaceae
Family Common Name:	Knotweed
Scientific Name:	Eriogonum marifolium Torr. & Gray
Common Name:	wild buckwheat; marumleaf buckwheat
Species Code:	ERMA4
Ecotype:	Crater Lake National Park, open dry meadows, 6,500 to 7,000 ft elev
General Distribution:	Washington, Oregon, California, Nevada; gravelly flats in lodgepole and ponderosa forest to alpine talus and ridges up to 9,000 ft elevation
Propagation Goal:	plants
Propagation Method:	seed
ProductType:	Container (plug)
Stock Type:	10
Time To Grow:	5 Months
Target Specifications:	well-branched fibrous roots should fill the conetainer; sturdy, well-branched crown growth
Propagule Collection:	Seed easily collected and fairly abundant in most years; hand-collected into paper sacks by pinching off the dry seed heads
Propagule Processing:	relatively large seed is easily screened by hand or office clipper to remove chaff with 1/16th screen, medium-low air flow.
Pre-Planting Treatments:	16 weeks o cold-moist stratification in walk-in cooler
Growing Area Preparation/ Annual Practices for Perennial Crops:	Seeds were sown into standard 10' conetainers filled with Fisons' Sunshine #3 seedling starter ; surface-sown seed covered with a fine layer of vermiculite; watered in and then covered with polyethylene sheeting and placed in a walk-in cooler at about 36 F for 16 weeks. We used 47 grams of seed for 1800 cones; these later had to be thinned and we would recommend about half that amount of seed in future seedings.
Establishment Phase:	Cones with stratified seed were moved to a warm sunny greenhouse at 70 + degrees day / 55 F night in April and watered lightly with mist nozzle until established.
Length of Establishment Phase:	Robust seedlings emerged fairly quickly; germination was complete within a month.
Active Growth Phase:	Plants watered early in the morning to minimize dampness overnight; fertilized lightly every other week with half-strength Peters Triple-20 NPK
Length of Active Growth Phase:	May to July
Hardening Phase:	Cones moved outdoors in June; fertilization discontinued in July; watering intervals gradually lengthened as roots developed .
Length of Hardening Phase:	4 weeks
Harvesting, Storage and Shipping:	Plants were shipped in August of the same year by refrigerated van to Crater Lake for outplanting in September.
Length of Storage:	unknown
Other Comments:	Shorter "stubby" cones could probably be used to produce these seedlings also and would make planting easier in shallow soil areas.
