Synthetic hormones are commonly used among producers of ornamental plants; however, they are costly, advice for application is required and cause adverse effects to the cultivation, environment and the producer, encouraging to seek alternatives capable of influencing the growth and flowering of the plant, so that, in the municipality of Zihuateutla, Puebla, Mexico, 14 homeopathic products were implemented in 2013 to reduce the size of the plant and induce flowering plants of white afelandra Aphelandra squarrosa var. snowflake (Acanthaceae). Supplying as irrigation water to the cuttings planted in pots, using 250 mL every 15 d for five times. At 90, 120 and 150 d after planting the cuttings plant height, leaf number, stem diameter and plant width was recorded. The bloom time is appropriated from the first flower formed to 150 d after planting. Data were analysed with nonparametric statistical test, using Kruskal-Wallis ranges without any significance in plant height, number of leaves and plant width. In the stem diameter, carbonic limestone 204 CH, Floral 30 CH, PFP 180 CH and bonzi make it decreased significantly at 120 d after planting. At flowering, early induction was obtained at 60% of the plants with the homeopathic preparation + vida 200 CH, which contains major and minor elements of 204 CH, rancid water, 214 CH, leachate 208 CH, mud 204 CH and mould 218 CH. This least-cost alternative will allow biorational, ecological, sustainable and organic ornamental production.
