Introducing the lifesaver cactus, also known as Huernia zebrina. Although it is referred to as the lifesaver cactus, the vibrant, circular flowers have a central opening that looks like the hole in a lifesaver candy, hence the name. This lifesaver cactus has many other names, such as owl eyes plant, lifebuoy Huernia, carrion flower, and zebra-striped Huernia.

Native to South Africa, Huernia zebrina has thick, fleshy stems that grow in a creeping manner. Your stunning lifesaver can grow up to 8 inches tall and 6 inches wide. These stems are covered in unique, dark green, triangular-shaped markings that resemble the pattern of a zebra. Hence, the plant gets its common name, "zebrina."

The flowers of the lifesaver cactus are truly captivating during the spring and summer. The center of these star-shaped flowers is adorned with raised, dark red or maroon markings that resemble the shape of a lifesaver candy, hence the nickname. The intricate design adds to the allure of the plant, making it a stunning addition to any succulent collection or garden. The lifesaver cactus flowers are not only visually striking but also emit an unpleasant aroma that attracts pollinators, such as flies. The odor is frequently compared to carrion, the decaying flesh of dead animals, which is why the flower is also known as a carrion flower.

Additionally, Huernia zebrina has no reported toxic effects, making it safe to use around pets and humans.

Watering Needs

Like other succulents, the Huernia zebrina lifesaver plant has specific watering requirements that are different from those of regular houseplants. Succulents, including the lifesaver plant, are adapted to survive in arid conditions and store water in their leaves, stems, or roots.

When it comes to watering the lifesaver plant, it's important to follow a "soak and dry" method. This means that you should thoroughly water the plant until the water drains out from the bottom of the pot, and then allow the soil to dry out completely before watering again. It's important not to keep the soil wet all the time because this can cause root rot and other problems.

Watering frequency is determined by several factors, including temperature, humidity, and pot size. As a general guideline, it's recommended to water the lifesaver cactus every 2-3 weeks during the growing season, which is typically spring and summer. In winter, when your Huernia zebrina is in a dormant state, you can reduce the frequency and water it sparingly.

Remember, it's always better to underwater than to overwater the lifesaver plant. If in doubt, it's best to err on the side of caution and let the soil dry out before watering again. Observing your lifesaver and checking the moisture level of the soil using your finger can also help you determine when it's time to water.

Light Requirements

This unique lifesaver succulent prefers bright, full sunlight to partial shade for optimal growth and health. In its natural habitat, the lifesaver plant thrives in semi-arid regions where it receives plenty of sunlight. When it comes to caring for your Huernia zebrina indoors, it's important to mimic its natural lighting conditions as closely as possible. Place your lifesaver plant in a location where it can receive bright, indirect sunlight for several hours a day. A south-facing window is often an excellent choice, as it provides ample light without exposing the plant to direct sunlight, which can cause sunburn.

If you don't have a south-facing window, don't worry! The lifesaver cactus can adapt to slightly lower light conditions but may grow more slowly. You can supplement its light requirements by using artificial grow lights, which can provide the necessary intensity and spectrum of light for your succulent growth.

It's important to note that while the lifesaver plant enjoys bright light, it's best to avoid placing it in direct sunlight, especially during the hottest parts of the day. Direct sunlight can scorch the leaves and cause damage to your Huernia zebrina. If you notice that the leaves are turning yellow or brown, it may be a sign that the succulent is receiving too much direct sunlight.

Optimal Soil & Fertilizer Needs

When it comes to the optimal soil for your Huernia zebrina, this unique succulent thrives in well-draining soil that mimics its natural habitat. For the lifesaver plant, it's best to use a well-draining cactus or succulent potting mix. These types of soil blends are specifically formulated to provide the right balance of moisture retention and drainage. To improve drainage, you can make your own mix by combining regular potting soil with perlite or coarse sand. Instead, make or buy a well-draining potting mix, or ideally, use our specialized potting mix that contains 5 natural substrates and mycorrhizae to promote the development of a strong root system that helps your lifesaver cactus thrive.

When it comes to fertilizing, the lifesaver plant doesn't require heavy feeding. In fact, it's generally recommended to use a diluted, balanced fertilizer specifically formulated for cacti and succulents. During the growing season, which is typically spring, you can fertilize your lifesaver plant once a year with an equal amount of NPK (5-10-5).

Remember, it's important not to over-fertilize the lifesaver plant, as this can lead to nutrient burn and other issues. Always err on the side of caution and use a weaker concentration than what is recommended, as succulents are adapted to survive in nutrient-poor environments.

Hardiness Zone & More

When it comes to temperature, the lifesaver plant prefers a warm environment. It thrives indoors in temperatures ranging from 60 to 80 degrees Fahrenheit. It's important to avoid exposing the plant to extreme temperature fluctuations, as this can cause stress and damage to the lifesaver plant.

If you are growing your lifesaver plant outdoors, it can thrive in USDA zones 9 to 11, which are regions with milder climates. These zones generally have average minimum temperatures ranging from 20 to 40 °F. If you live in a colder climate, it's best to keep the lifesaver plant indoors or provide it with protection during the colder months.

In terms of humidity, the lifesaver plant is adaptable and can tolerate a range of humidity levels. However, it generally prefers lower-humidity environments similar to its native habitat. Aim for a humidity level of around 40 to 50%, which is considered average indoor humidity. If the air in your home is particularly dry, you can increase humidity by using a humidifier or placing a tray filled with water near the plant.

Remember, providing the lifesaver plant with the right temperature and humidity conditions and appropriate hardiness zone considerations will help ensure its health and vitality.

Propagating Lifesaver Plant

Propagating this unique lifesaver plant Huernia zebrina can be done through various methods, including stem cuttings and seed propagation. For stem cuttings, you can take a healthy stem from the plant and allow it to dry out for a few days to form a callus. Then, you can plant the stem in well-drained soil and provide it with indirect sunlight and minimal watering. Over time, new roots will develop, and a new plant will begin to grow. Seed propagation is another option, where you can collect the seeds from mature flowers and sow them in a well-draining soil mix. With patience and proper care, you can successfully propagate the lifesaver plant and expand your collection of these fascinating succulents.

The Bottom Line

Overall, the lifesaver plant Huernia zebrina is a captivating succulent that never fails to grab attention with its unique star-shaped flowers. These blooms, with their striking dark green or brownish stripes resembling a zebra pattern, add a touch of whimsy to any garden or indoor space. Taking care of the lifesaver plant is relatively easy, as it thrives in bright, indirect sunlight and well-draining soil. Whether you choose to propagate it through stem cuttings or seeds, with a little patience and proper care, you can expand your collection of these fascinating succulents.
