Best Garden on the Web

Like common yarrow, woolly yarrow is well-suited to the Iowa garden. Cold tolerant, drought tolerant, and prolific, woolly yarrow is not as invasive as common yarrow (due to its smaller height of 3-6 inches). A good groundcover, it is well-suited for rock gardens. If you are looking for a plant that is easy to grow and prolific, woolly yarrow is an excellent choice.

Please note that the Zones listed above are USDA Hardiness Zones and are only given as a rough indication of whether a plant will grow and thrive in your area. Temperature variations and unusual weather conditions can affect plant survival. To assist plant survival during the winter, you may wish to place mulch over the areas in question or plant the flowers in an area away from walls or cement. Additionally, digging up bulbs and roots to overwinter indoors may be preferrable to keeping them in the ground.
