Dactylorhiza sambucina - Elder-flowered Orchid

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.
