Most yellow shasta daisies tend to remain yellow for just a day or two before turning white. 'Luna' shasta daisy sends up pom-pom type yellow flowers that become two-tone (deep yellow eye with lighter yellow petals) for about two weeks before fading to white. This variety stays a tidy mound, about 18" tall and wide, and will keep blooming into the fall, especially if spent blooms are removed. 'Luna' is an excellent choice for container planters or along garden borders, and will attract bees and butterflies.
