Description: This tall cryptocoryne can be used as a background or middleground plant and adapts easily to a wide range of conditions. The leaf color depends on a number of factors, including lighting, and varies from an olive-green to green and slightly brown. The underside is usually a light orange-brown color. Plant it in spaced groups, allowing it to spread and create a dense clump.
Cryptocoryne wendtii must be undisputedly the most recommendable Cryptocoryne for aquarium cultivation. It ideally combines a decorative appearance with optimal growth. Several growth forms are commercially available which, without exception, are suitable for emersed cultivation. A shaded location is adequate for ensuring good growth. The plants are adaptable to water values and will prosper in soft and hard, as well as weak acid or alkaline water. Multiplication occurs rapidly through runners so that dense communities will develop after a couple of weeks. The optimum temperature range lies between 22 and 26 °C, but both higher and lower temperatures can be tolerated over short periods. The emersed cultivation of Cryptocoryne wendtii, too, is unproblematic, if conditions of high humidity and a nutrient-rich substrate are provided. The latter, for example, may consist of a loam-sand mixture. The inconspicuous inflorescences develop quite often.
