The term "carrion" is used to describe the unpleasant, foul odor associated with decaying flesh. This Stapelia gigantea gets its common name because its flowers emit a strong, unpleasant, carrion-like smell, which resembles rotting meat. The odor is what attracts flies and other pollinators in their natural habitat.

Despite their unusual smell, the flowers of the Stapelia gigantea can be quite beautiful and captivating. They are a testament to the diversity and uniqueness of nature. If you ever come across these flowers, be sure to take a moment to appreciate their intricate beauty, even if the smell might not be to everyone's liking! 

When and How to Water Your Carrion Plant 

The Carrion Plant is a highly drought-tolerant succulent, meaning it can store water in its thick stems and survive long dry spells. Overwatering is one of the most common mistakes with this plant, so it’s important to mimic its natural dry habitat by keeping watering minimal. The carrion plant prefers watering once every 2-3 weeks in the growing season, and once in 4-6 weeks during the dormant season.

In spring and fall, during the growing season, the carrion flower plant prefers watering once every 2–3 weeks is sufficient, but frequency should be adjusted depending on your conditions, such as temperature, humidity, and soil drainage. Using the soak and dry method, water thoroughly until excess drains out of the pot, then wait until the soil has completely dried before watering again. 

In winter, during the dormant season, the Carrion plant slows down its growth to watering once every 4–6 weeks, or even less, is usually enough. During this period, allow the soil to stay dry for extended periods, watering only when the stems show signs of dehydration, like slight wrinkling. Providing too much water in dormancy can lead to root rot, so it’s best to keep it on the drier side.

Light Requirements - Where to Place Your Carrion Plant

When growing your Stapelia gigantea indoors, it thrives in bright, indirect light for 4-6 hours a day. Avoid placing it in direct sunlight, as the intense rays can scorch the leaves and cause damage to the carrion plant. If you notice that the stems are stretching or leaning toward the light source, it's a sign that it needs more light. In that case, you can consider supplementing with artificial grow lights to provide the necessary brightness. 

When growing outdoors, it works best in full sun to partial shade. It can tolerate some direct sunlight, especially during the morning or late afternoon, but it's best to avoid the scorching midday sun. A location with dappled sunlight or a spot under a tree that provides filtered light can be ideal for the carrion plant. Just make sure it still gets enough brightness to thrive. 

Remember, finding the right balance of light is crucial for the health of the Stapelia gigantea. Too much direct sunlight can cause sunburn and damage the plant, while insufficient light can lead to weak growth and poor blooming.

Optimal Soil & Fertilizer Needs

The Carrion plant prefers a well-draining soil mix and should be fertilized once a year in spring.

The Stapelia gigantea carrion plant doesn't require frequent fertilization, but it can benefit from light feeding during the growing season. Fertilize once a year during the growing season in the spring with a balanced NPK fertilizer of about 5-10-5. Be cautious not to over-fertilize, as this can result in excessive growth with fewer blooms. This provides a slow-release source of nutrients and helps improve the overall soil structure. 

Hardiness Zone & More 

In the United States, this is mostly an indoor plant, but if you live in southern Florida or Hawaii, then you can cultivate it outdoors in USDA zones 10-12.
