Orchis purpurea - Lady Orchid

Phylum: Magnoliophyta - Class: Liliopsida - Order: Orchidales - Family: Orchidaceae

The specimen shown above was photographed in the Lot Valley, southern France, in late May.

In the UK the Lady Orchid is now rare and limited to a few sites in southern England. It is easier to find this orchid in France or Italy where it still flowers freely in some places. In the Gargano Peninsula area of southern Italy the plants can grow to a metre in height and have large, densley-packed infloresences of vividly marked flowers.

Description

The Lady Orchid grows up to 80 cm tall and has a basal rosette 3 - 8 large erect leaves which are glossy green and unmarked. The flower spikes of the Lady Orchid can contain anything up to 200 individual flowers. The upper sepals and petals from a dark red hood above the lip of the flower which is white and strongly marked with deep red. The shape and markings of the lips of Orchis purpurea are extremely variable but there is no mistaking a Lady Orchid when you have found one - its sheer size and vivid white and dark red flowers confirm that it is unlikely to be anything else.

Distribution

The Lady Orchid is now rare in the UK and found in only a few sites in Kent and Oxfordshire. It is more common in parts of Europe where it occurs from Denmark in the north to Spain, Italy, Greece and North Africa.

Habitat

Favouring alkaline or occasionally neutral soils, the Lady Orchid occurs in short grassland, on woodland edges and sometimes in open woodland. In the UK it associated almost exclusively with woodland habitats; however, it is found in open scrubland in other parts of Europe.

The plant shown above was photographed in mid-April on a roadside in southern Italy, and there were numerous other specimens of similar stature in the vicinity.

Flowering times

In the UK this orchid flowers in May and June. Further south in Europe it comes into flower in April.

Hybrids and Varieties

Two rare hybrids have been reported in the UK:

• Orchis x wilmsii is a hybrid with Early Purple-orchid Orchis mascula
• Orchis x meilsheimeri is a hybrid with Man Orchid Orchis anthropophora.

In Oxfordshire there is a well known site with hybrids between Lady Orchid and Monkey Orchid, which is known by the scientific name Orchis x angusticruris, often referred to as Lankey Orchids.

Etymology

The genus name Orchis means 'testacles', a reference to the twin tubers of orchids in this genus. The specific epithet purpurata means 'purplish'.
