Description
Herbaceous perennial growing from rhizomes, from one to several stems up to heights 10 dm.[2] Tripinnate and lance-shaped leaves evenly distributed along stem with the leaves becoming smaller towards the top. Leaves typically between 1/4 inch to 1 1/4 inch wide and 1 1/4 inch long to 6 inches long. Inflorescences flat-topped, containing 10-20 whitish to yellowish,[3] typically radiate pseudanthia.[4] Fruits are achenes.[2]
Bloom Period
April-October [2]
Distribution
"Widespread throughout North America" [3]
Habitat
Common in open dry to moist areas from high to low elevations; drought tolerant [2]
Uses
Several tribes of the Plains region of the United States including the Pawnee and Chippewa tribes used common yarrow. The Pawnee used the stalk in a treatment for pain relief. The Chippewa used the leaves in a steam inhalant for headaches. They also chewed the roots and applied the saliva to their appendages as a stimulant. The Cherokee drank a tea of common yarrow to reduce fever and aid in restful sleep. [3]
Herbalist Michael Moore also writes that A. millefolium is a great benefit for acute fevers as a hot infusion, that it is an effective hemostatic, and that it helps with irritation of the GI mucosa. [5]
Propagation
Clean seeds with hammer mill then air screen cleaner. Sow in field between May or June and September. Plant 50-70 seeds per foot 1/2" deep or less spaced in 3" rows.
Seed
Seed sample from: 2011
Average Measurement: 1.9 x 0.6 x 0.3
Measurement Range: L: 1.6 - 2.1, W: 0.5 - 1, D: 0.2 - 0.5
Features
Shape: Seed narrowly winged at margins, thicker in the middle. Seed face is narrower at hilum end, broadening at opposite side.
Color: Seed coat papery and white, becoming transparent at the center to reveal a red-brown inner seed.
Surface: Finely longitudinally ridged.
Latitudinal Cross Section: elliptical 
Longitudinal Cross Section: obovate 
Basic Explanations and Assumptions:
The dimensions for the seeds are length x width x depth. The location of the hilum is used as the base of the seed, and the length is measured from hilum to the opposite apex. Where a style is present, the length is measured from the hilum to the bottom of the style. Width is measured at a right angle to the length at the widest part. Depth is measured at a right angle to the intersection of height and width lines.
Measurements included are the mean average for each measurement of ten separate seeds.
All measurements in millimeters unless otherwise noted.
