Stephania nova is a caudex, whiich has big round zen looking foliage. Stephania needs very well-drained soil, bright shade to bright sun, and airy, not excessively humid conditions.Caudiciform plants do not require much maintenance. Because they are able to store water for dry periods, you do not need to water them regularly. During the months of active growth, water sufficiently only when the soil is completely dry. Avoid watering when the plant is hibernating; foliage dies back, which is when you should begin watering it very minimally—perhaps only twice a month. Do not overwater, as the caudex will rot and your plant will die.
