A beautiful little orchid whose labellum shape vaguely resembles the Purple Orchid (Orchis purpurea) from a distance. But upon closer observation, the differences quickly become apparent. The plant measures between 10 and 30 cm and bears a variable inflorescence of tiny helmet-shaped flowers (sepals and petals join together to form a hood over the labellum). The labellum is white, speckled with small purple dots, while the hood is purple, varying in intensity.

This orchid can be found across much of the country, except in northern France, and flowers from May to early July, depending on region and altitude (up to 2000 m). It can be abundant or rare depending on the biotope, and quickly disappears if the surrounding vegetation becomes too dense, as it prefers short-grass meadows.

There is a subspecies or variety (Neotinea ustulata var. aestivalis) that flowers in July, mainly in the Alps, and is said to be taller, with a more developed flowering spike. It's not easy to determine whether this is truly a distinct variety or simply a late flowering form of the type species, as there are no known sites where both types bloom at different times. Having observed plants in bloom in July in Savoie (where N. ustulata usually flowers in May in other French departments), I still cannot tell them apart! Morphologically, there is no obvious difference — even though N. ustulata var. aestivalis is sometimes described as “taller,” one can find equally tall individuals of the type species elsewhere. The mountain climate and altitude may also explain the later blooming time.

However, in the Essonne region, N. ustulata can be observed in May, and the species or its variety aestivalis blooms in nearby Seine-et-Marne (just 25 km away) from mid-June — with a time gap of nearly six weeks, despite nearly identical climate and altitude. This would seem to support the reality of a variety with a delayed flowering period. The flowers of the aestivalis variety also appear slightly more robust. Notably, its blooming is highly irregular from year to year (a ratio of 1 in 10 at least), which is not the case for N. ustulata, which flowers abundantly and consistently in May. Late spring weather events may explain this irregularity. Still, this is the only population known in the area and is highly localized. Does a temporally shifted flowering in such a micro-population justify naming it a separate variety ?
