Eichornia crassipes

Invasive Alien Species of Union concern

Origin: Tropical South America (Northeasetern Brazil, French Guyanase, Surinam, Venezuela).

First finding in Slovenia: Not yet found in nature in Slovenia.

Pathways: Formerly an ornamental plant for aquaria and garden ponds, importing transport and selling are banned since 2016. 

Possible to find: March-October

Flowering season: April-August

Habitat: Eutrophic lakes and rivers. In Europe, the temperatures are at the lower limits for this tropical plant (this species dies at temperatures below 8’C), therefore permanent populations can only be expected at thermal springs. 

Status in Slovenia: There are no confirmed findings of this species in Slovenian nature. Despite the ban in 2016, it still may be (un)intentionally introduced because it used to be a commonly cultivated plant. Due to the climatic constraints, this is especially a problem in the Primorska region and at thermal springs. 

Similar species: none.
