The favourable climatic conditions make Brazil one of the most important producers of tropical flowers, among them some Heliconia native species are remarkable. In the present study 19 accessions of H. chartacea were characterized using morphological descriptors related to pseudostem, leaf and inflorescences. The purpose was to select accessions with desirable aspects for cut flower production. The experiment was carried out during August 2014 and January 2015. Differences were observed in morphological descriptors related to the inflorescences. In 54% of the inflorescences that were harvested, the length was between 30 and 60 cm and varied according to the number of open bracts. The width was larger than 40 cm in 75% of the inflorescences. About 70% of the harvested stems had weight above 200 g and the average stem diameter was between 20-30 mm. The latter feature was directly related to the stiffness of the flower stem. The length of the peduncle varied between 10 and 20 cm for 60% of the stems. The vase life of the flower stems ranged between 5 and 11 days. In general, most of the studied accessions were suitable for use as cut flower, nevertheless more detailed evaluation is necessary.
