PARTS AND SHAPE OF THE PLANT

Standards: Upper part of the flower (3 in number).

Falls: Lower part of the flower (also 3).

Beards: Clusters of hairs at the throat of the falls. Their differing colours constitute a decorative element.

Style: visible between the falls, can also add decorative interest.

Stalk: Its size varies between 15 cm and 120 cm depending on the variety.

Branching: Ramifications of the stalk. They should be regularly spaced so that each flower can bloom freely.

Substance or Body -the "body" or texture of the standards and falls contributes to the robustness of the flowers.

Rhizome: Fleshy underground part, which helps the plant get through the winter.

Seedling: New hybrids are obtained by sowing seeds from crossed varieties. The term seedling generally denotes a non-registered variety.

 

COLOUR CATEGORIES

Amoena: Irises that have white standards and tinted falls.

Bicolor: Irises with different coloured standards and falls.

Plicata: Irises with 2 or sometimes 3 colours, but not in the same patterns as on amoena or bicolors. Plicata have petals that are rimmed, dotted or stitched with colour, often on a white or yellow background.

Variegata: (not to be confused with 'variegated' which refers to leaf colour). Describes irises with standards that are between yellow & copper, with red to brown falls.
