Serapias parviflora, the small-flowered tongue-orchid,[1] is a species of orchid native to the Mediterranean Basin and the Atlantic coast of Europe.

[2] Serapias parviflora is found natively across the Mediterranean Basin from the Iberian Peninsula to the Aegean Sea, as well as in the Canary Islands and along the Atlantic coast of France.

[2] That colony disappeared after 20 years, but in 2021, 16 plants were discovered growing on the 11th-floor biodiverse green roof at Nomura International's office building in the City of London.

The most plausible explanation for their arrival is wind blown seed on a weather phenomenon such as those which frequently bring Saharan dust storms to the city in spring.

NOMURA are working with Kew Science laboratories and mycologists to study the orchids and hope to shed further light on their arrival in the future.
