Sansevieria masoniana: The Whale Fin Snake Plant

The Sansevieria masoniana, commonly known as the Whale Fin Snake Plant, is a tropical plant native to the Democratic Republic of Congo. It is a part of the Sansevieria genus, which consists of various species of popular house plants. What sets the Sansevieria masoniana apart from other Sansevieria varieties is its unique and distinctive appearance. The leaves of this plant are gigantic, paddle-shaped, and have a mottled green pattern that resembles the skin of a whale.

Light Requirements

When it comes to lighting, the Whale Fin Snake Plant thrives in bright, indirect light. It can tolerate low light conditions, making it a great choice for those areas in your home that receive less natural light. However, to promote optimal growth and maintain the vibrant color of the leaves, it is best to place the plant in an area with medium to bright indirect light. If possible, providing the plant with a few hours of direct sunlight in the morning is also beneficial. Just be cautious not to expose it to intense, direct sunlight for an extended period as it can scorch the leaves.

Watering and Soil

One of the key factors in successfully caring for the Sansevieria masoniana is getting the watering and soil conditions right. This plant is drought-tolerant and can survive with minimal watering. It is important to allow the soil to dry out completely between waterings to prevent root rot. As a general rule, water the plant thoroughly and then wait for the top few inches of soil to dry out before watering again. During the growing season (spring and summer), you can water the plant once every two weeks. In contrast, during the dormant season (fall and winter), reduce watering to once a month.

When it comes to soil requirements, the Sansevieria masoniana prefers well-draining soil. A mixture of succulent/cactus potting mix and pumice or perlite is an excellent choice. This combination ensures that excess water drains away quickly, preventing the plant from sitting in water. Terra cotta pots are preferred as they allow the soil to dry out more rapidly. However, any pot with proper drainage holes can be used.

Temperature and Humidity

The Sansevieria masoniana is a versatile plant that can adapt to a wide range of temperatures. It thrives in average room temperatures between 65°F to 75°F (18°C to 24°C). However, it can tolerate temperatures as low as 60°F (15°C) and as high as 85°F (29°C). Avoid exposing the plant to cold drafts or sudden temperature changes, as it can stress the plant and hinder its growth.

In terms of humidity, this plant is not particularly sensitive and can tolerate average indoor humidity levels. Maintain a humidity range of around 40% to 50%. As with most house plants, it is beneficial to provide occasional misting or place a pebble tray filled with water near the plant to increase humidity.


The Sansevieria masoniana is not a heavy feeder and requires minimal fertilization. During the growing season (spring and summer), you can fertilize the plant with a balanced houseplant fertilizer diluted to half strength. Apply the fertilizer every 1-2 months, following the instructions on the package. Over-fertilization can lead to root burn and damage the plant, so it is essential to avoid excessive fertilization.


Propagating the Sansevieria masoniana can be done through various methods, including division, leaf cuttings, and water propagation. Division is the fastest method and involves separating the root clumps into smaller sections. Make sure each section has some healthy roots and foliage before potting them up individually.

For leaf cuttings, choose a healthy leaf and cut it into sections of about two inches each. Allow the cuttings to callus over for a few days before planting them in well-draining soil. Keep the soil lightly moist, and new roots will develop from the cuttings. Another option is water propagation, where you place the leaf cuttings in water until roots grow, and then transfer them to soil.

Common Problems and Solutions

While the Sansevieria masoniana is a relatively low-maintenance plant, it can still face a few common issues. One problem that may arise is curled leaves, which is often due to soil moisture issues. To remedy this, give the plant a thorough top watering or water it from the bottom to re-wet the dry potting mix. Use room temperature or lukewarm water to prevent shocking the plant.

Pests such as spider mites, mealybugs, and scale insects can occasionally infest the Sansevieria masoniana. Regularly check the plant for signs of infestation, such as webbing, specks, or sticky residue. If pests are detected, treat them with insecticidal soap or neem oil to eliminate the problem.


In conclusion, the Sansevieria masoniana, or Whale Fin Snake Plant, is a remarkable house plant that will bring a touch of elegance and uniqueness to your indoor space.
