Growing by the side of the water, long wide grassy leaves with stiff round stems, each with two or three large bluish flowers at the top. Between 2 - 3 flowers per (un-branched) main stem.

Two spent flowers below the third still extant flower. Three striped blue and white with yellow bracts droop downwards. Three all-blue 'petals' spread out horizontally, whilst another three all-blue petals stretch upwards. [In reality, Irises have but three petals, the rest are sepals or other structures].

The blue of the petals is mid-way to being mauve.

The outer sepals are strikingly patterned in purple stripes over-laying yellow, perhaps a warning of its toxicity, and reminiscent of the discordant purple on yellow patterning on the flowers of Henbane.

Fawn and orange-coloured sheaths (actually called 'spathes') at the juncture of bifurcating flower stalks.

The long wide sword-shaped leaves are slightly translucent at the edges.


Flower pattern of 3 + 3 + 3 'petals' similar to other flowers of the Iris Family. There are only three real petals, the others are sepals of one sort or another.

Some similarities to :

  • Purple Iris (Iris versicolor), which is also found in Yorkshire on the River Calder (which flows through Hebden Bridge) but has between 2 to 9 flowers per main stem and deeper yellow coloration down the middle of the outer three sepals. and wider leaf-like spathes half-encircling the top parts of the stems.
  • Butterfly Iris (Iris spuria) which is also purple with yellow but has 2 to 4 flowes per main stem and is rare in the UK, being confined to ditches in Lincolnshire and Dorset.
  • Garden Iris aka Bearded Iris (Iris germanica) but that is somewhat branched, has larger flowers (20 - 35mm wide) 3 to 4 flowers per main stem (only 2 - 3 for Siberian Iris) but most prominently a swathe of white stamens with yellow anthers on the upper and narrow parts of the three outer 'petals'.

Like many other Irises, Siberian Iris contains the cardiac poison Iridin.
