The Cora vinca series from seed is derived from the same genetic background as the vegetative Nirvana series. Thus, in addition to possessing other positive traits that result from hybridization, Cora varieties also exhibit a high tolerance to aerial Phytopthera. The
hybrid vigor produces a high rate of useable seedlings along with a uniform habit and tight bloom window across the series. Large, striking flowers with overlapping petals are held over glossy green foliage.
