Yarrow is an interesting evergreen ground cover that can be used to spruce up a border or fill in a bald spot in your garden with its green, dainty, fern-like leaves and its pretty clusters of white flowers. Yarrow spreads through underground runners and self seeds eagerly all while impeding the growth of weeds making it a valuable horticultural selection for your garden. Medicinally, it has the ability to slow down bleeding, kill a cold or sweat out a fever, aid in digestion and makes a great poultice. If one makes true compost tea (by forced aeration), throw in a handful of leaves and watch the bubbles explode! Great for regular compost too! Yarrow is a wonderful plant to grow as a natural border in between the grass and the larger bushes. The grass won’t pass and the yarrow spreads away from the shade, leaving the bush to its own devices.
