Introduction: Limonium sinuatum (L.) Mill. does not appear in the book of Vascular Plants of Cuba, although it is grown by farmers as an ornamental plant, mainly due to the variety of colors in its flowers. Objective: to identify an appropriate mixed substrate, based on invasive aquatic plants, for L. sinuatum, in its first 28 days of crop. Method: 150 alveoli were prepared, 30 with Typical Red Ferralitic Soil (control) and the rest with substrate mixed with soil and dry mass of Pistia stratiotes L. (0.5 and 1.0 %) and Eichhornia crassipes (Mart.) Solms (2.0 and 4.0 %). After 28 days of culture, 30 experimental units per treatment were selected and their morphological characteristics were analyzed. Results: the emergence percentage was higher (45 %) in the experimental units where substrate mixed with E. crassipes was applied. Greater fresh (7.7 g) and dry (0.65 g) mass was obtained with P. stratiotes (1.0 %). The average number of leaves was greater where substrate mixed with E. crassipes (2.0%) was used, and the average length and width of the leaves was greater where substrate mixed with P. stratiotes (1.0 %) was used. Conclusion: the experimental units of L. sinuatum, grown with Typical Red Ferralitic Soil and dry mass of P. stratiotes at 1.0 %, as a mixed substrate, presented more relevant morphological characteristics than the rest of the experimental units. This is considered the most feasible treatment in the seedling phase. It is necessary to apply these substrates until the reproductive phase of L. sinuatum.
