Don’t let this mounded, compact grower fool you: 'Marshmallow' Yarrow tough, excelling in dry to average gardens and growing where salty soils, sandy soils, or those with low fertility hold other plants back. Thanks to slender, deep green leaves and a dense form, these plants are attractive spring through fall and are adorned with generous crops of frilly, pom-pom like flowers for months in summer. The flowers of 'Marshmallow' Yarrow make excellent cut flowers and dry well. A great pick for gardeners in most of the US; those in hotter dryer areas, like the Southwest, should site this plant in sites with average or greater moisture, while those in moister locales, like the Midwest, should site this plant in drier spots.
