It is a shrubby, very branched plant that can reach up to 2-3 m in height. It has cylindrical, tuberculous stems, up to 4 cm in diameter, on the top of which large leaves grow, up to 15 cm long, of a light green color, spatula-shaped and with a slightly dented apex. Euphorbia poissonii is a deciduous plant, which means that it loses its leaves during the period of vegetative rest and then regenerates them. Before producing new foliage, small greenish-yellow flowers with red stamens bloom on the plant. The species name honors Henri Louis Poisson - a French botanist, who discovered and described this variety. Important: when the plant is damaged, its poisonous and very irritating latex comes out, so if this happens, be careful not to touch your eyes or mouth and wash your hands with soap.
