Description

Herbacious 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 as they get closer to 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 white flowers. http://plants.usda.gov/java/profile?symbol=acmi2

Bloom Period

Distribution

Widespread throughout North America http://plants.usda.gov/java/profile?symbol=acmi2

Habitat

Common in open dry to moist areas from high to low elevations; drought tolerant http://biology.burke.washington.edu/herbarium/imagecollection.php

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.

Achillea millefolium


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.
