It has erect stems which grow to 60cm, and much shorter (15-35mm) linear leaves emanating at intervals from around the stem much like grass leaves do.

The flowers are usually violet-blue but can sometimes be purple, pink or white. They are in bunches on short petioles which emerge from some of the leaf junctions.

Not to be confused with: Spider Brake (Pteris multifida), Early Spider-Orchid (Ophrys sphegodes), Late Spider Orchid (Ophrys fuciflora) [species from other families with similar names]

Could be mistaken for : an Iris such as Siberian Iris (Iris sibirica) but that has much larger petals as well as two other sets of three blue-violet petal lookee-likees.

An introduced survivor grown in gardens but escaping into waste places where it is tipped by gardeners.It can be found in the deep south of the UK, such as the Isle of Wight, Guernsey, Jersey and a few scattered locations further north especially around London. The version usually grown in gardens is a hybrid, possibly of Tradescantia virginiana (purportedly this) with another species, but it is not known which other species.
