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 | |
