Family Scientific Name: Plumbaginaceae
Family Common Name: leadwort
Scientific Name: Armeria maritima
Common Name: sea thrift
Species Code: AMMA
Ecotype: Coastal ecotype from Clatsop Co, OR
General Distribution: Mountains and coastal regions within the Northern Hemisphere.
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 filling soil profile in container.
Pre-Planting Treatments: Armeria maritima seeds germinated at higher percentages when they received cool (35 degree F) treatments as opposed to the 75 degree growth chamber immediately. The difference in germination rates was 86% and 66% respectively and the seedlings in the warm treatments were moldy and appeared less vigorous. A short cold treatment followed by temperatures of 50-60 degrees Fahrenheit would probably be the best germination strategy for this species.
Harvesting, Storage and Shipping: Seed may be short-lived in storage. Germination trials were repeated with the same seed lot, one year later (when seeds were 5 years old) and germination rates were greatly reduced. More studies are required with this
