Family Scientific Name: Fabaceae
Family Common Name: Pea
Scientific Name: Oxytropis campestris (L.) DC. gracilis (Nels.) Hult.
Common Name: Field Oxytrope
Ecotype: Central, South-Central Alaska; dry, sandy areas
Propagation Goal: plants
Propagation Method: seed
ProductType: Container (plug)
Time To Grow: 0
Target Specifications: Root trainer, 10.5 cu.in./cell. Multiple leaves, firm root plug.
Propagule Collection: By hand when pods start opening. The seeds are ripe when brown and hard.
Propagule Processing: Air dry. Approximately 500 seeds per gram. Tetrazolium test: 85+% viable seed. Clean seed with brush cleaner then hand screen. Store in freezer.
Pre-Planting Treatments: Our best germination occurred when seeds were planted into cells in the fall and subjected to ambient temperature fluctuations. In spring seeds start germinating at approximately 50 degrees F. With a Tetrazolium test of 96%, eleven days after bringing cells into greenhouse, 92% of seeds had germinated.

If seed is to be planted in the spring here in Alaska, a slight scarification (fine sandpaper) enables germination to occur. Germination is less.
Growing Area Preparation/
Annual Practices for Perennial Crops:		 Soil mix: Upland, well drained. Plant 2 seeds per cell. If planted in the fall, bring into greenhouse by end of March. If planted in the spring, initial propagation site is greenhouse.
Establishment Phase: Plants moved to lathhouse to harden off after last frost. Fertilize minimally after true leaves appear.
Length of Establishment Phase: Two months
