Sassy Summer Lemon Yellow Yarrow

Achillea 'Sassy Summer Lemon' is an upright yarrow introduced by Walters Gardens in its Sassy Summer collection. Fine, silvery-green foliage frames sturdy stems of bright yellow flower clusters from early summer into midsummer. ## Landscape Use Use it in sunny perennial borders, pollinator plantings, or repeated groups; its stems also suit cut-flower arrangements. Walters Gardens lists mature plants at 28–32 inches tall and 36–42 inches wide. Give it full sun and well-drained soil; overly rich conditions can make stems loose. US Plant Patent PP31693 was granted on April 21, 2020. [Walters Gardens](https://www.waltersgardens.com/variety.php?ID=ACHSL) identifies its growing traits; the [patent record](https://patents.google.com/patent/USPP31693P2/en) describes it as an Achillea hybrid and documents the grant date. Walters Gardens notes that the flowers attract bees and butterflies and can be used as cut flowers. ## Seasonal Interest The patent describes flowering from early June into mid-July in Michigan. Local timing shifts with climate. ## Maintenance Plant in a sunny, freely drained site. Remove faded stems when they no longer contribute to the display and cut back old growth as needed in spring.
