This bright lemon-yellow flower is composed of tufted spikes, each individual flower made-up of two closed lips, the lower with two orangey bosses and a spur which points downwards. The green, narrow leaves grow spirally up the stem.
It flowers late into the autumn giving a bright flush of colour, from July to October. Pollination usually requires strong insects such as bees and bumblebees to open the closed flower lips.
Usually found in clumps in meadows, roadsides, embankments, and other open grassy habitats. Common and widespread throughout.
