Lobelia Persicifolia, also known as “Poison Grass” or “Zèb pwazon” in Creole, is a subshrub endemic to Guadeloupe that can reach 1.5 meters in height. It is characterized by a very leafy stem accompanied by flaccid leaves, up to 25 cm long and 4 cm wide, sometimes serrated or smooth. Its red flowers form an inflorescence visible mainly between October and May.
Classified as a ZNIEFF (Natural Zones of Ecological, Faunistic and Floristic Interest) defining species, it indicates that the natural environment in which it grows has a greater heritage value than the surrounding areas.
This erect annual plant was used by Native Americans, who crushed it in rivers to stun fish and facilitate their capture, hence its nickname.
More widespread in Basse-Terre, this plant is found mainly on the edges of humid forests and along forest roads, at altitudes between 450 and 800 meters, sometimes even lower (up to 150 meters).
Threats
This species is not particularly threatened, but due to its endemic nature, it is important to remain vigilant to prevent any degradation of its natural habitat.
