Purslane, madeira vine, american fireweed, pigweed, fameflower: wild edible plants.
Purslane (Portulaca oleracea L.), madeira vine (Anredera cordifolia (Ten.) Steenis), american fireweed (Erechtites spp.), pigweed (Amaranthus spp.) and fameflower (Talinum paniculatum (Jacq.) Gaertn.) are considered invasive plants in commercial crops, urban areas and gardens. These plants are used as food, at least regionally, replacing or complementing the conventional vegetables, supplying the needs of fiber and vitamins. They are rustic plants, with high adaptability, therefore, easy to grow, being an alternative for family farmers who could grow them saving on buying seeds, fertilizers and pesticides, inputs usually necessary for the production of conventional vegetables.
