I grew Yarrow for the first time just because I was trying to fill up an herb garden. Had I known what a beautiful plant this was I would have had it at the top of my list instead of just using it as filler. Yarrow has the most attractive fern like foliage. Yarrow has a bunch of uses as a medicinal herb. If you are trying to grow organically, Yarrow needs to be on your list. It is a great companion plant for repelling insects. It also attracts beneficial insects. It is a must have herb. Yarrow has a place in my garden and it should have a place in yours too.
