Coreopsis auriculata ‘Zamphir’

2 Photos


Coreopsis auriculata ‘Zamphir’ forms a low mound of foliage with fluted, golden-yellow flowers from May through June. The fluted petals set this cultivar apart from other selections of C. auriculata; however, we found this characteristic to be unstable. One plant perished over the first winter, but the remaining four plants began the second season as healthy clumps. Powdery mildew and leaf spot began to appear during during the spring of 2013, greatly affecting plant health. By the end of 2013, all plants of ‘Zamphir’ were in very poor condition and failed to return the following year. However, of the three Coreopsis auriculata cultivars we tested, ‘Zamphir’ proved to be the most vigorous.
