Helleborus x hybridus is the name given to any of a wide variety of acaulescent ( stemless ) hellebores grown in gardens. The flower has an unusual structure, with the colour deriving not from petals, but from sepals. Inside the sepals is a ring of nectaries (green), then the anthers, and finally, in the centre, the carpels and pistils. H x hybridus is self-fertile and genetically diverse. This results in the appearance of many offspring, each with slightly different colours and patterns on the sepals. The picture shows a series of flowers from a garden in Norfolk, UK. The original plant was purple and spotted ( 3, below centre ). The other flowers in this picture are from self-sown, open-pollinated progeny of this plant. The plant above the purple original has purple spots on a pale background. The pattern of the spots is different on each sepal, as can be seen throughout the picture.
