A bunch of flowers occupies each nook where a leaf emerges from the main stem. The petals un-twist as the flower opens. Purple stripes adorn the outer surface of the petals. Note the two pale-green triangular bracts beneath each whorl of flowers.

Flared like a euphonium, and with a brass-coloured inner. Most flowers have three anthers, much fewer have five.

The petals have longitudinal dark stipes, whilst the inner has a golden-yellow glow. In common with all other 'eyed-grasses' the petals have a pointed 'spike' at the tip.

The tiered-whorled nature of the flowers is more apparent when they are in fruit. Stem apparently square (at least where the flowers are).

Petals flared and recurved outwards like other' eyed-grasses'. Both fruits and flowers larger than Blue-eyed-Grass.

Purple stripes more apparent on external surface of petals, the central one more prominent than the rest. bulbous fruits strangely reminiscent of something.

Some flowering spikes grow much longer than do others.

The sword-like leaves are a glaucous green, and unlike other 'eyed-grasses' are not grass-like in the same very narrow way, but more like those of the Iris (Iridaceae) family.


Some similarities to : Blue-eyed Grass, American Blue-eyed-Grass, Yellow-Eyed-Grass and Veined Yellow-eyed-Grass. [Which are all in the same Sisyrinchium genus - none of which are Grasses].

A member of the Iris Family.

Some similarities to: some Helleborines such as Marsh Helleborine.

More likely to be found in a garden than growing wild. It is non-native to the UK but is to South America where it has a great propensity to spread uncontrollably, but is short-lived in the UK and found on tips and other waste ground as a garden throw-out and has a strong presence in the Home Counties and the Welsh Borders.

Uniquely identifiable characteristics
