Medicinal plants with ornamental potential: a study in the cerrado of Mato Grosso State, Brazil.


The introduction of exotic vegetal species in Brazil replaced the use of the native ones in the landscaping in the major of the cities. Nowadays, the number of exotic plants used for ornamentation is incomparable higher than the natives. However, it is evident that various typical cerrado species have a really expressive ornamental potential. In this manner, this work lists 50 medicinal species from cerrado, which can be used for the ornamentation of urban and rural areas. Considering the former studies and a recent screening of the medicinal plants from the cerrado of Mato Grosso State, the species that have interesting ornamental characteristics have been selected. Among the taxa suggested as ornamental, the highest number of species was found in the family Bignoniaceae (with 6 species) and in the genera
Anadenanthera (with 3 species). The suggested species are predominantly arboreous (58%), but there are also herbaceous (16%), shrubby (12%), undershrubby (8%), one cactus, one creeper and one palm tree. The most expressive characteristic was the flowering period (26,5%), then the foliage (25%), the architecture (21,5%), the fructification (18%) and the trunk (9%). These species are suitable for planting in home gardens, public squares and parks, for shading and hedges or under the electric light mains. There is also the advantage of some food species that attract birds (humming-birds, parakeets, parrots and others). The best techniques for propagation of the species and the growing conditions have although to be established.
