Crossandra infundibuliformis (L.) Nees is a highly valued ornamental perennial species, with attractive orange flowers and dark green leaves, cultivated in temperate regions as an indoor plant. The objective of this study was to evaluate the influence of three fertilizers, in concentration of 0.2% (Bionat Plus, Green Feed and Cropmax), on vegetative growth and flowering of plants. The results indicated that the foliar application of these fertilizers caused a significant increase in most of the studied morphological parameters, compared to the control plants. The highest values of plant height (40.35 cm), number of shoots per plant (7.81), leaf length (8.78 cm), leaf width (4.63 cm), number of flowers per spike (18.93), and spike length (8.62 cm) were recorded in plants sprayed with Bionat Plus. Plants fertilization with Cropmax increased the number of spikes per plant, and also promoted the earlier flowering, recording the lowest number of days from planting to flowering (81.33 days).
