Achillea millefolium (Western Yarrow) w/ Lawn Replacement

Achillea millefolium, Western Yarrow is a long-lived flowering perennial that starts blooming in April and doesn't stop until it's time for snow again, we regularly have Yarrow blooming in snowstorms. Yarrow has been used for thousands of years for a wide spectrum of medicinal purposes, we are unfamiliar with these and recommend you do your own research. It can be considered aggressive, especially where it isn't native but in a healthy wild yard or garden it does not outcompete other established vegetation. It is also easy to remove/control if kept from seeding. Hardy in zones 3-9                                              

Tolerates and often prefers poor, rocky and sandy soils but enjoys loam and compost also. It has extreme cold, heat and drought tolerance, needs no supplemental water if started from seed in the fall. Most often found in dry sage steppe into dry forest floors, such as foothill Ponderosa or Oak stands. But is found in almost ecotypes of the intermountain West. Once established this requires no irrigation and will also tolerate poor, rocky soil.  It is also fire resistant with low ignitability and can be used as a fire break in native and permaculture yards.
