This plant is named for an ancient goddess, Artemis.
The specific name, tridentata, is because of the three teeth
commonly found on the end of each leaf. Many of the leaves
on the photo to the left show this characteristic.
The leaf surfaces are covered with short silvery white hairs.
This is an adaptation to minimize evaporation and conserve water.
These hairs give the plant its typical grayish green color.
It blooms in late summer and early fall, but the flowers are not
showy. They are cream colored, and very tiny. However they grow
in dense clusters, and can produce a large amount of pollen.
