Hygrophila Difformis, is found in marshy habitats on the Indian subcontinent in Bangladesh, Bhutan, India and Nepal. It requires a nutrient-rich substrate, also CO2 fertilization, and iron-rich fertilizer is recommended. Provide a moderate amount of lighting of at least 2 to 3 watts per gallon of full spectrum (5000-7000K) light. For Wisteria to thrive, the water should be kept between 74°-82°F, with a pH of 6.5-7.5. To propagate, plant cuttings that have been removed from the healthy mature plant. Simply remove any leaves from the bottom 1″ to 2″ of the stem, and new root growth will form from the last node on the stem. It can be easily propagated from cuttings.
