Observations on Elide asparagoides and Polygala myrtifolia in Corsica, FranceElide asparagoides (= Asparagus asparagoides, Liliaceae) is an ornamental species originating from South Africa. This plant is a geophyte producing climber stems up to 2.5 m long. The plant is known to be naturalized in Portugal (including Azores), Sicilia (Italy), South of France (including Corsica). This plant is known to be very invasive in Australia. According to a field survey made in 2002, the plant is expanding in Corsica. This study provided useful information on its biology and ecology. It is not known by local horticulturists but is supposed to have escaped from gardens. E. asparagoides is heliophile, susceptible to drought and its seeds are thought to be propagated by birds. This plant has a long growing period (from October to April) and produces very rapidly a huge biomass and a lot of seeds. It has a wide ecological tolerance (it grows from 0 to 210 m of altitude). E. asparagoides could represent a threat to indigenous species having the same life cycle as Prasium majus (Lamiaceae) which is rare in Corsica. Although the species is stopped by dense vegetations, its extension is favoured by transportation routes (roads, paths ...) and fires. This plant might cover large surfaces in the future and become very invasive. It should be monitored and contained.Source:
