Yarrow is a staple in so many gardens and it blooms and grows all the better if it's used as a cut flower. 'Cerise Queen' is one of the best new cultivars, with vibrant pink blooms that just keep coming.
Growing yarrow in full sun will help keep it from flopping. Yarrow also needs to be divided periodically, maybe every 4-5 years or so, to keep it blooming well. Other than that, sit back and enjoy.
