Platanthera chlorantha.
Platanthère verte.
Greater butterfly orchid.
Rather widespread outside of a few departments, this orchid can be found from sea level up to 2000 meters. It grows in open meadows and in shaded areas from the end of April until July for high altitude stations.
In metropolitan France, we also find Platanthera bifolia. Differentiating the two is not easy from a morphological point of view: from 20 to 60 cm, the same shades and similar leaves. It will therefore be necessary to approach it closely and observe the inside of the flower. The anthers are distant and trapezoidal in shape for chlorantha and tight and parallel for bifolia. The first views of these two species will therefore illustrate this point.
