A magnificent large-flowered variety, Clematis 'Guernsey Cream' produces an abundance of luminous flowers, 5-6 in. across (12-15 cm), that cover the foliage entirely. Opening pale yellow, the rounded, overlapping petals are adorned with pale chartreuse central bars. As the blooms mature, they fade to creamy white and contrast pleasantly with the prominent yellow anthers. The flowers are followed by large, showy silver seedheads, which add further interest to the plant. Flowering comes in two waves: first in late spring and early summer, then in late summer and early fall.
