The flowers of 'Sarah' are of a good size. The tepals with crimped edges vary between light pink and lavender blue, the median being the darkest, giving a two tone aspect, even as buds. Once open, the umbrels have the advantage of staying really straight, like a candelabra, which is remarkable in an agapanthus. They don't produce any seeds. The evergreen plant is resistant down to – 8°C.
