All-America Selections says, "Sweet Daisy™ Birdy Leucanthemum is a beautiful perennial with robust, long-lasting blooms and carefree longevity in gardens down to zone 3. In the AAS Trials, it demonstrated excellent cold and heat tolerance and maintained a tidy, sturdy habit over the three-year trial. The cheery flowers are large and pure white in color, appearing earlier in the season than the comparison varieties. The 5″ reflexed daisy blooms feature small feathery petals around golden yellow button centers. Leucanthemums, also known as Shasta Daisies, are used for both cut flowers and garden highlights while also providing food and habitat for many kinds of pollinators. Enjoy this beauty in the garden as a medium-height bright spot (great for moonlight gardens) that will provide years of beauty with very little maintenance other than deadheading spent blooms if desired, but not necessary."
