    Common yarrow can be quite invasive and difficult to control. They spread through roots, which is why you have been having some issues with controlling it with Round-up. It just does not get deep enough with a surface application. This is a plant that needs to be dug up. I would recommend digging up as much as you can, then applying either Round-up or boiling water to the area where it was, to kill off any of the remaining roots. Be aware that both Round-up and boiling water will kill whatever plant growth it touches.

    It's quite common for yarrow to change color. This is because the natural color is white, and a variety of hybridizing and genetic manipulation techniques are required to produce colors. With time and/or stress, the plant reverts to its natural white. Stress would probably include too much water, or too much fertilizer.

    This can happen with newly planted perennials. The blossoms may be nearing the end of their lifespan and transplant shock can cause the flowers to brown and fade. Dead head the spent blossoms, and water your new plants daily for the first 2 weeks, then you can cut back.
    You may receive new flowers again, but most likely you will need to wait until next summer for the plant to bloom again.

    Garden Yarrow is a perennial Herb, that is both decorative and considered an invasive weed!
    I often times allow them to flower and then pull them up shortly after to help control the spread of these plants.
    Here are some articles for you.
