Guernsey Cream is a large-flowered perennial vine that climbs 6 to 8 feet tall. From May to June, it produces 5-inch flowers that emerge light yellow with green central bars and gradually fade to creamy white as they mature. Smaller flowers bloom again from August to September. Plant Guernsey Cream in full sun to partial shade, and prune it in late winter or early spring. Remove the dead stems, and cut the remaining shoots back to 6 to 9 inches above a couple of well-developed buds.
