Achillea millefolium, or common yarrow, is a herbaceous flowering plant in the Asteracae family. Sometimes also called western yarrow, millefoil, bloodwort, carpenter's weed, plumajillo, and hierba de las cortaduras.

Abbreviation Code (Codon): ACMI


Description

Herbaceous perennial growing from rhizomes, from one to several stems up to heights of 8 to 16 inches. 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. Flat-topped flower heads (inflorescence) containing 10-20 whitish to yellowish flowers. [1]

Bloom Period

April-October [2]

Distribution of Yarrow

Distribution

"Widespread throughout North America" [1]

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. [1]

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

Achillea millefolium


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 ACMI-lat-crosssection.png

Longitudinal Cross Section: obovate ACMI-long-crosssection.png

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.
