    I guess you'd have to call this a green eyed susan. Typical yellow daisies, but with greenish yellow central cones rather than the classic dark brown. Two three feet tall or so, blooming extremely heavily over a long period from late summer into fall. This form seems to be a bit more inclined to perennialize than some of the selections. Zone 3

    Finely textured grasses make fantastic companions to these golden beauties. Each flower is tipped in lemon yellow with green center disks. Provide moist, organic soil that is well-drained for blooms all summer and fall.

    By: Select Seeds

    Bright 4-6" deep primrose yellow daisy-like blooms with dark centers are born mid-summer to fall. The flowers are held on sturdy stems that are 2-3'H. An excellent butterfly nectar plant. Moderately drought tolerant once well established.

    Summer skies incarnate! This beauty (my favorite of all the R. hirta hybrids) sports a clear lemon central disk & can brighten up any Fall garden, particularly if you’re trying to steer clear of the Autumn bronzes, which are lovely in their own right, but not for everyone. Grows to 2’ tall & wide & prefers a sunny locale. Pair with Asperula orientalis “Sweet Blue Woodruff” or plant in front of Pycnostachys urticifolia for a sassy contrast or with the purples of Caryopteris incana for a lovely complimentary planting to carry you through till Winter, though I’ve known these plants to winter over & keep on blooming if deadheaded!
