Family Scientific Name: Chenopodiaceae
Family Common Name: Goosefoot Family
Scientific Name: Krascheninnikovia lanata (Pursh) A. Meeuse & Smit
Common Name: Winterfat
Ecotype: Madrean Archipelago
General Distribution: Found on slopes and plains, sometimes on alkaline soils from 2,000–7,000 ft (500-2100m) (Ogle et al., Flora of North America Editorial Committee 1993+). Does not tolerate excessive moisture or acidic soils (Ogle et al.). Important forage for both livestock and wildlife (Ogle et al.).
Propagation Goal: Plants
Propagation Method: Seed
ProductType: Container (plug)
Propagule Collection: Collect by hand when seeds are easily separated from plant. Bracts surrounding seeds should be brownish and slightly crumbly. If they are green and flexible, the seeds are not ready.
Propagule Processing: Seeds are fairly delicate and can easily be damaged. For this reason, it is advisable to maintain viability by leaving the four-winged, white fluffy bracts on the seed for storage and planting (Ogle et al.). Seed can generally be stored for 1-2 years under optimal conditions (dry, 5°C). However, viability may decrease by as much as 50% in the first year of storage and it decreases drastically after 2-3 years of storage (Ogle et al., Majerus 2003). For this reason, seed should be planted as soon after collection as possible.
Establishment Phase: Germination rates rely heavily on the age of the seed. Fresh (1-2 years old) seed germination rates are typically 85-95% but seed 3 years old or older has germination rates of 0-15%, even under optimal storage conditions (Ogle et al., Majerus 2003). Seed should be sowed on soil surface or up to ¼ inch deep, but no deeper (Ogle et al.). It is unknown if removing the bracts has any effect on germination rates, so this may be something to test (Majerus 2003).
