Family Scientific Name: Asteraceae
Family Common Name: Composite, Aster, Daisy, Sunflower
Scientific Name: Erigeron foliosus
Common Name: Leafy fleabane
Species Code: ERFO2
Ecotype: Rogue River-Siskiyou National Forest, Oregon
General Distribution: Grows in dry, often rocky soils. Found in Oregon and California and parts of northwestern Mexico. Some sources also show a disjunct population in southern Washington.
Propagation Goal: Plants
Propagation Method: Seed
ProductType: Container (plug)
Stock Type: 262 ml (16 in3) container
Time To Grow: 20 weeks
Target Specifications: Stock Type: Container seedling Root System: Firm plug in container.
Pre-Planting Treatments: Due to small seed size, the easiest method is to sow seed into trays filled with stabilized medium plugs (Q-plugs). Trays are sealed inside plastic bags and placed into refrigeration at 1 to 3 °C for 70 days. Trays are checked weekly and kept moist throughout the stratification period. If mold is evident, trays should be treated with 1% hydrogen peroxide.
Growing Area Preparation/
Annual Practices for Perennial Crops:		 Greenhouse growing facility.
Q-plugs are lightly covered with nursery grit. Seedlings are transplanted to target containers approximately 3 weeks following removal from stratification.
Growing medium used is 40:20:20:20 peat:composted fir bark:perlite:pumice with Nutricote controlled release fertilizer (18N:6P2O5:8K2O with minors; 180-d release rate at 21C) at the rate of 1.5 gram Nutricote per 262 ml container.
Establishment Phase: Germination is uniform and quite rapid. It is usually complete in 10 to 14 days. Following germination (while still in Q-plugs), plants are fertilized with soluble 12-2-14-6Ca-3Mg at 75 ppm for 1 week.
Length of Establishment Phase: 2 weeks
Active Growth Phase: Root development is somewhat slow. Shoot growth can be considered moderate throughout the active growth phase, but can be pushed to reach target height and plug density in the first year. Soluble fertilizer (20-9-20 NPK, 20-18-18 NPK, or 17-5-24 NPK) at 150 ppm is applied weekly throughout the growing season.
Length of Active Growth Phase: 18 weeks
Hardening Phase: No dry-down is done to induce dormancy. Seedlings are moved to an outdoor growing area in late September.
Length of Hardening Phase: 3 to 4 weeks
Harvesting, Storage and Shipping: Harvest Date: Early October
Storage Conditions: Seedlings are usually outplanted in fall. No storage except in outdoor growing area. Plants are well irrigated prior to shipping and shipped in containers.
Other Comments: Perennial
5 recognized varieties: var. confinis (CA and OR), var. foliosus (CA), var. franciscensis (CA), var. hartwegii (CA), and var. mendocinus (CA).
