Dorstenia - Foetida aka Shield Flower or Green Fig
Dorstenia foetida, commonly referred to Shield Flower or Green Fig is an intriguing and somewhat unusual succulent-like plant appreciated by collectors for its unique appearance and fascinating reproductive structures. Native to arid regions, this member of the Moraceae (mulberry) family develops a stout caudex and distinctive, often oddly shaped, green "flowers" known as hypanthodia. Its curious features make it a conversation starter and a captivating addition to collections of the more bizarre and wonderful plants.
Key Features of Dorstenia foetida
- Caudex: Develops a fleshy, swollen stem base (caudex) that serves as a water storage organ. The caudex can vary in shape and size, often becoming quite sculptural with age.
- Foliage: Produces relatively small, often lobed or wavy, green leaves that emerge from the upper parts of the caudex and stems. The leaves are typically deciduous, especially during drier or cooler periods.
- Hypanthodia (False Flowers): The most striking feature is its unusual inflorescence called a hypanthodium. These are flattened, disc-like or irregularly shaped green structures that bear the tiny, inconspicuous true flowers embedded on their surface. They can sometimes have tentacle-like appendages.
- Scent: The species name "foetida" refers to the sometimes unpleasant odor emitted by the flowers to attract specific pollinators, though this scent is not always strong or noticeable.
- Latex: Like other members of the Moraceae family, it contains a milky sap (latex) that can be irritant to some individuals.
Care for Your Dorstenia foetida
- Light: Prefers bright, indirect sunlight. While it can tolerate some direct morning sun, intense afternoon sun should be avoided to prevent scorching.
- Soil: Requires a well-draining soil mix, such as a cactus and succulent blend amended with extra perlite or pumice.
- Watering: Water thoroughly during the active growing season (typically spring and summer) when the plant has leaves, allowing the soil to dry out between waterings. Reduce watering significantly or withhold water during the dormant period when leaves are shed.
- Temperature: Prefers warm temperatures and is not frost-tolerant. Protect from freezing conditions.
- Humidity: Tolerates average indoor humidity levels. Good air circulation is beneficial.
Maintenance for a Healthy Plant
- Repotting: Repot every 1-2 years or when the caudex has significantly outgrown its container. Choose a pot only slightly larger with good drainage. Spring is usually the best time for repotting. Be careful not to damage the fragile roots.
- Pruning: Generally does not require pruning, except to remove dead or unsightly stems.
- Pest Control: Monitor for common pests like spider mites and mealybugs. Treat any infestations promptly with appropriate methods.
- Fertilizing: Fertilize sparingly during the active growing season with a diluted balanced liquid fertilizer formulated for succulents. Avoid over-fertilizing.
Propagation Methods for Dorstenia foetida
- Seeds: Propagation is primarily through seeds, which can be obtained from mature plants after successful pollination. Sow seeds in a well-draining mix and provide warmth and humidity. Germination can be erratic.
- Stem Cuttings: Stem cuttings can sometimes be rooted, but success rates can be variable. Allow the cut end to callus for a few days before planting in a well-draining medium. Provide warmth and humidity.
Dorstenia foetida is a truly unique and fascinating plant that appeals to those who appreciate the unusual and the intricacies of the natural world. Its stout caudex and peculiar hypanthodia make it a captivating specimen that adds a touch of the bizarre beauty of arid flora to any collection.
