Dorstenia foetida is a small caudex-forming succulent with thick dark green to mahogany-colored stems and light green lanceolate leaves. It is a very variable species, especially in the size and shape of leaves and length of petioles and stipules. The caudex grows up to 16 inches (40 cm) tall and 6 inches (15 cm) in diameter. Flowers are small, grayish or green, and up to 0.8 inches (2 cm) across.
USDA hardiness zones 10b to 11b: from 35 °F (+1.7 °C) to 50 °F (+10 °C).
How to Grow and Care
Dorstenias are warm-loving plants, and they need a bit more water than regular succulents. They need a well-drained potting mix, and their water needs vary depending on the season of the year. Water your Dorstenias regularly to abundant from spring to fall. Allow the soil to dry slightly between watering, but ensure that they never dry out completely. These plants tend to go at least partially dormant during the winter months. During this period, water very little. Giving plants a warm, sunny position can result in beautiful compact growing plants. Fertilizing plants once in a while during their growing period with a high potash and phosphorus fertilizer is recommended.
The spring weather with a high-temperature swing between the day and night hours and pretty frequent rains can favor the development of fungus diseases, which should be treated preemptively with a systemic fungicide.
Dorstenias are generally propagated by seed. Many species are self-fertile. Their seeds are expelled explosively from the mature seed heads and are liable to populate pots several feet away. They can also be propagated by cuttings.
