Antennaria rosea heads containing pistillate flowers. The fruit is an achene with a body less than 2 millimeters long and a pappus which may be 6 or 7 millimeters long. The plant often produces fertile seeds, but most individuals in most populations are clones. Plants are sometimes fertilized with pollen from other "Antennaria" species, which may bring new genes into an "A. rosea" population, increasing the genetic diversity amongst the clones. Antennaria rosea Antennaria rosea is a North American species of flowering plant in the daisy family known by the common name rosy pussytoes. It is widespread across much of Canada including
