Dactylorhiza sambucina - Elder-flowered Orchid
Phylum: Magnoliophyta - Class: Liliopsida - Order: Orchidales - Family: Orchidaceae
This orchid occurs in two colours, red and yellow. They frequently appear together, although the red flowers tend to bloom slightly earlier than the yellow ones.
Description
A somewhat short and stumpy looking plant, this orchid grows to around 30cm in height. The 4 to 7 basal leaves are unspotted and pointed at their tips. The large flowers can be either reddish or yellow, and there are rare appearances of salmon pink intermediate forms; they are large and are carried on a lax inflorescence.

The common name refers to the flowers' slight scent, which resembles that of elder flowers.
Above: the reddish form of Dactylorhiza sambucina is almost as common as the yellow form in some sites, including this roadside verge near Les Rives, in southern France.
Distribution
The Elder-flowered Orchid grows in Finland, Sweden and Norway and as far south as southern France. It also occurs in some central European countries including Bulgaria, Slovenia and Romania.
Above and below: This orchid has two colour forms, yellow and red. Intermediates can occur but in most locations appear to be rather uncommon.
Elder-flowered Orchids favour calcareous or sometimes slightly acid soils and grow in pastures, mountain meadows and grassland, often in great numbers.
Habitat
The specimens shown here were photographed near Murat, southern France, in early June.
Flowering times
Dactylorhiza sambucina flowers from April to the end of June. The red form flowers slightly earlier than the yellow form.
Etymology
The genus name Dactylorhiza means 'finger-like roots', while the specific epithet sambucina is a reference to Sambucus nigra, the Elder tree. These orchids have a scent similar to that of flowers of the Elder tree.
