Which species is noted as being common in the region alongside common yarrow?

• A. Western yarrow (Achillea lanulosa)
• B. Common dandelion
• C. Chickweed
• D. Goldenrod

Answer: (A)

Both yarrow species grow in similar habitats in the region, so they’re often found together. Western yarrow is another Achillea species that commonly occurs alongside common yarrow in the same areas—meadows, roadsides, and disturbed soils—making it the expected companion in regional notes. The other plants listed are common weeds in turf or lawn areas, but they aren’t typically described as co-occurring with common yarrow in this region, so they fit less well as the noted companion.
