Family Scientific Name: Asteraceae
Family Common Name: Aster
Scientific Name: Liatris punctata
Common Name: Dotted Gayfeather
General Distribution: Found growing on the drier plains and hills of Manitoba and Saskatchewan, south to Texas and Arizona. It is drought resistant and well adapted to a variety of upland prairie sites. Dotted gayfeather is common on shallow soils or on heavier loam soils.
Propagation Goal: Seeds
Propagation Method: Seed
Product Type: Propagules (seeds, cuttings, poles, etc.)
Propagule Processing: EASE OF COLLECTION: Hand collected or mechanically harvested with combine. It often grows taller under fertile conditions, and stems supporting inflorescences may tend to lodge and make mechanized harvesting difficult.
METHOD OF CLEANING: Initially utilized hammermill with 3/16 screen at 500 revolutions per minute (RPM’s) to remove achenes from inflorescence. Desktop, two-screen cleaner with top screen 12 x 1/2 and bottom screen 1/25 utilized to remove inert material from achenes. Material hand rubbed using rub board between operations of the desk top cleaner.
TYPE OF MATERIAL COLLECTED FOR PROPAGATION: Seed (achene) or bulb-like caudex.
PROPAGATION METHOD: Seed. Germination of dotted gayfeather requires no pretreatment. Highest germination percentages of dotted gayfeather were exhibited when an alternating temperature regimen of 95/68ºF was utilized. The plants can be successfully transplanted in early spring while in a dormant condition.
NUMBER OF SEEDS PER POUND: There are approximately 139,000 seeds per pound with this Liatris species.
PERCENT GERMINATION: Varies with seed quality.
Pre-Planting Treatments: PRETREATMENT USED: None.
Growing Area Preparation/
Annual Practices for Perennial Crops:

METHOD OF GROWING: Standard methods employed.
Harvesting, Storage and Shipping: SEED MATURITY DATE: Fall.
STORAGE REQUIREMENTS: Another Liatris sp. has retained viability for 12 years under controlled temperature and humidity conditions at the Manhattan Plant Materials Center. This may or may not apply to dotted gayfeather.
ESTIMATED PROPAGULE STORAGE POTENTIAL: Data unavailable at date of publication.
