Family Scientific Name: Apiaceae
Family Common Name: Carrot family
Scientific Name: Perideridia gairdneri Hook. & Arn
Common Name: Gairdner's yampah
Species Code: PEGA3
Ecotype: seeds were collected in Lane Co., Oregon near Eugene
Propagation Goal: plants
Propagation Method: seed
ProductType: Container (plug)
Time To Grow: 0
Pre-Planting Treatments: Seeds were sown directly into cone-tainers filled with Sunshine#1 (a soil-less peat-based media) amended with micro-nutrients (Micro-max) and a slow-release fertilizer (Osmocote 14-14-14). Flats of cone-tainers were covered with poly-ethylene bags and placed in a walk-in cooler (35-40 degrees). Seedlings emerged after 80 days. 80% germination was observed.
Growing Area Preparation/
Annual Practices for Perennial Crops:		 When seedlings emerged, flats were removed from the cooler and placed in a greenhouse set at moderate temperatures (70 degree day/ 50 degree nights).
Establishment Phase: Seedlings germinated within one to two weeks after coming out of the cooler.
Other Comments: Trials were also conducted with no cold-moist stratification which resulted in zero germination, 6 weeks cold-moiststratification resulted in fair germination 40%. 80-90 days cold-moist stratification is optimum.
