[4] William Hooker described a plant that he concluded had smaller deeper-yellow flowers than A. schottii in cultivation in Exeter as Allamanda neriifolia.
[6] Allamanda schottii is found in the south and southeast of Brazil, in the states of Espírito Santo, Minas Gerais, Rio de Janeiro, São Paulo, Paraná and Santa Catarina.
In Brazil, it grows near or alongside bodies of water, often in wet areas, in open or closed forests.
[6] Allamanda schottii has become naturalised in Puerto Rico, the Galapagos Islands and Costa Rica.
