Are you looking for a unique and fascinating house plant to add to your collection? Look no further than Huernia macrocarpa, also known as the starfish flower. With its distinctive star-shaped flowers and low-maintenance care requirements, Huernia macrocarpa is a wonderful addition to any indoor garden. In this article, we will explore the various aspects of caring for Huernia macrocarpa, including lighting, watering, soil requirements, and propagation methods. So, let’s dive in and discover everything you need to know about this intriguing house plant!

Lighting Requirements

Huernia macrocarpa thrives in bright, indirect sunlight. It is best to place the plant in a spot that receives plenty of bright, indirect light throughout the day. However, direct sunlight should be avoided as it can cause damage to the plant’s leaves and stems. If you notice that the leaves are turning yellow or brown, it may be a sign that the plant is receiving too much sunlight. Providing some shade during the hottest part of the day can help protect the plant from excessive light exposure.

Watering and Soil

One of the key aspects of caring for Huernia macrocarpa is proper watering. This house plant is drought-tolerant and requires minimal watering. Watering should be done sporadically, only when the top layer of soil appears dry. During the summer months, you can water the plant about once a week. However, during the winter dormancy period, watering should be reduced to once a month or even less. Overwatering can lead to root rot, so it’s crucial to let the soil dry out between waterings.

When it comes to soil, Huernia macrocarpa requires a well-draining medium. Using a cactus or succulent potting mix is ideal as it provides good drainage. Avoid using heavy, clay-based soil that retains too much moisture. A mix of cactus potting soil, sand, and perlite can create a suitable growing medium for Huernia macrocarpa.

Fertilizing and Pruning

Huernia macrocarpa benefits from monthly fertilization during the summer months. Use a diluted succulent or cactus fertilizer to provide the necessary nutrients. However, it’s important to stop fertilizing during the fall and winter when the plant is in its dormant phase. As with most succulents, Huernia macrocarpa does not require frequent feeding.

While regular pruning is not necessary, you can pinch off the tips of the stems to promote bushier growth. If you notice any dead or damaged stems or leaves, it’s best to remove them with clean scissors to prevent the spread of disease. Pruning can also be done after the plant has finished blooming to encourage new growth.

Propagation Methods

Propagating Huernia macrocarpa can be done through stem cuttings. To propagate, cut off an offshoot from a mature plant, allowing it to dry for a few days. Then, plant the cutting in a pot filled with fresh cactus potting mix. It’s important to provide adequate sunlight and slightly damp soil during the initial stages of growth for the cutting to establish roots.

Common Issues and Pests

Huernia macrocarpa is relatively pest and disease-resistant. However, it may occasionally attract mealybugs, spider mites, and scale insects. Regularly inspect the plant for any signs of infestation, such as webs or sticky residue, and treat promptly with neem oil or insecticidal soap. Avoid overwatering to prevent fungal diseases like root rot or powdery mildew.


In conclusion, Huernia macrocarpa, or the starfish flower, is a captivating house plant that can bring a touch of uniqueness to your indoor garden. With its star-shaped flowers and low-maintenance care requirements, it is an excellent choice for both experienced gardeners and beginners. Remember to provide bright, indirect sunlight, water sparingly, use a well-draining soil mix, and fertilize during the active growing season. Additionally, consider propagating Huernia macrocarpa through stem cuttings for expanding your collection. Keep an eye out for common pests and diseases, and take appropriate measures to treat them promptly. Enjoy the beauty and charm of Huernia macrocarpa as it thrives in your home!
