Tournfort introduced plant grouping by genus. refers to the eminent French botanist, Joseph Pitton de Tournfort (1656-1708). He built upon the foundations of the past too. Linnaeus’ own work did not emerge from a vacuum. Our scientific understanding has progressed. Not every aspect of his system has stood the test of time. It is remarkable that we refer back to so much of his groundbreaking work today. An error could never erode the importance of his work. Linnaeus’ classification system is a phenomenal piece of work. The error traces all the way back to Linnaeus in his Species Plantarum of 1753, as signalled by the L. ![]() ![]() Some botanical detective work is necessary to find out why. Linnegar and Hewitt advise that Bearded Irises are often incorrectly called Iris germanica L. Emma Cook Pattern: darker ring of colour around the edge of the falls.Broken Colour: standards and falls with splotches, blotches and streaks in random patterns.Bicolour: standards and falls of two different colours other than the colours specified in Amoena, Variegata or Neglecta above.Reversed Bitone: standards and falls of the same colour, but the standards are a darker shade than the falls.Bitone: standards and falls of the same colour, but the standards are a lighter shade than the falls.Laminata: development of plicata with a more solid, darker colour and often with a halo around the beard. ![]() Glaciata: pale-coloured standards and falls without any purple anthocyanin pigment.Neglecta: pale blue standards with deeper blue falls.Variegata: yellow standards with red falls (also maroon or brown falls possible).Amoena: coloured falls with white standards.Picotees have different colour edges to main flower. Breeders have extended the colour range to pink and apricot. Traditionally, these appeared on white or yellow. Plicata: stippled, dotted or stitched edges.Self: standards and falls are the same colour.Their colourful glamour is so much sought-after that they have their own specialist vocabulary. Tall Bearded Irises are the cultivars that most readily spring to mind when we think of Bearded Irises. ![]() Tall, pale blue Bearded Irises in an RHS Chelsea Flower Show display in 2017 © Karen Andrews Specialist Standard and Fall Terms Bearded Irises are further split into the following size-related groups that are commonly described with standard acronyms: The British Iris Society website splits Irises into 6 sections with very clear photos demonstrating the plant variation at a glance: Bearded Irises, Siberian Irises, Iris reticulata, Dutch Iris, Iris pseudacorus and Iris laevigata. Iris and Bearded Iris Groupsīefore venturing into subtle details, let’s look at the various groups of Irises and Bearded Irises recognised today. There is a completely separate and specialist Iris vocabulary to describe all these distinctions. Noted features are also veining, lines and dots. Iris-lovers enthuse about the contrasts in colour between the beard, standards and falls. Falls are the 3 lower petals that fall gently downwards. Standards are the 3 uppermost, upright petals of a Bearded Iris. The beard acts as a landing pad for pollinators. In addition to the beard, specialist terms to describe Bearded Iris flowers are standards and falls.
