Dissémination de Dactylorhiza fuchsii (Druce) Soó dans les pelouses d'un jardin suburbain.

Having appeared in 2002 in the author's suburban garden, a single plant of Dactylorhiza fuchsii gave rise, by April-May 2023, to a population of 764 plants in a vegetative state, of which 32% were flowering in June. The generative dispersal of the orchid throughout the lawn suggests that the symbiotic fungus is also present everywhere in the soil. The ecology of the orchid is discussed, taking into account the rather acid and by no means calcareous nature of the oligotrophic soil of the garden. [ABSTRACT FROM AUTHOR]
