Family Scientific Name: Asteraceae
Family Common Name: aster
Scientific Name: Ericameria nauseosa
Common Synonym: Chrysothamnus nauseosus
Common Name: rubber rabbitbrush
Species Code: ERNAN5
Ecotype: High elevation ecotype at Lassen National Park, Ca
General Distribution: This plant may be found in the central swath of North America from Texas and New Mexico to North Dakota and Montana primarily in shrub land areas.
Propagation Goal: plants
Propagation Method: seed
ProductType: Container (plug)
Stock Type: stubby containers
Time To Grow: Weeks
Target Specifications: Well-developed crowns, roots and rhizomes that fit the soil profile in container.
Pre-Planting Treatments: Ericameria nauseosa seeds germinated both with and without a cool treatment in our trials. However, when placed directly in our warm growth chamber (70F days and 50F nights)we saw only a 62% germination. This rate improved to 82% when given a two week cool (38F) treatment. The germination rate again dropped (to 78%) when the cool treatment was extended to 90 days. In summary, it appears that a brief cool treatment prior to a warm growth chamber is ideal for germination.
