The present work is a study of "everlasting flowers" as a natural product of importance for interior decoration. The term "everlasting flowers" is used for scapes and inflorescences which, even after being detached from the plant, still maintain the appearance of living structures. The economic activities related to this group of plants are considered; their importance is demonstrated, as a source of income and employment in the region of Diamantina (State of Minas Gerais, Brazil), and also as a source of revenue for the country: production is largely exported to Europe and the U.S.A. A survey was made of the quantity of such flowers marketed, of prices paid to collectors, and of the wholesale prices of the species most extensively commercialized in the region (18 Eriocaulaceae, 10 Gramineae, 3 Xyridaceae and 2 Cyperaceae); from these figures were calculated the values involved in production and commercialization, thus providing some idea of the income created and the quantity of plants concerned. The importance of exportation of everlasting flowers as a source of revenue was also considered. Analysis of data permits inference of a decline in export; this may be due to a fall in production as a result of over-collection and subsequent difficulty in recuperation of populations, or of market competition from other countries. It is suggested that research should be increased with a view to making viable the systematic cultivation of those species which can be cultivated, as an important contribution to the economy of regions of campo rupestre
