Sansevieria cylindrica ‘Starfish’, commonly known as Starfish Sansevieria, is a unique and sought-after houseplant. Its distinctive appearance makes it a popular choice for adding an architectural element to indoor spaces. This plant is known for its sculptural form and low-maintenance nature, appealing to both seasoned plant enthusiasts and beginners.
Understanding Your Starfish Sansevieria
The ‘Starfish’ variety of Sansevieria cylindrica features short, thick, cylindrical leaves that fan out from a central rosette, resembling a starfish. These stiff, tubular leaves often display light green foliage with darker green concentric circles or bands, and can have silvery-green hues. Unlike other snake plant varieties that grow tall and upright, the ‘Starfish’ cultivar is more compact, typically reaching about 8 to 16 inches in height. This fan-like growth habit contributes to its unique aesthetic.
Essential Care for Starfish Sansevieria
Light
Starfish Sansevieria thrives in bright, indirect light conditions, such as from an east or west-facing window. While it can tolerate lower light levels, insufficient light may slow its growth and cause leaves to lose vibrancy. Direct, intense sunlight should be avoided, as it can scorch the leaves and lead to browning.
Watering
Overwatering presents a significant risk for Starfish Sansevieria, as its thick leaves store water and excess moisture can lead to root rot. Allow the soil to dry completely between waterings. A thorough watering, ensuring all roots are hydrated and excess water drains, is preferable to frequent, shallow watering. During the growing season, water every one to two weeks, reducing to about once a month or less in winter.
Soil
This plant requires a well-draining soil mix to prevent waterlogging and root decay. A cactus or succulent potting mix is ideal, providing the necessary aeration and drainage. Creating a custom mix with equal parts potting soil, sand, and perlite or pumice can also provide a suitable environment.
Temperature and Humidity
Starfish Sansevieria prefers average room temperatures, thriving between 60°F and 85°F (15°C to 29°C). While it can tolerate slight variations, protecting it from temperatures below 50°F (10°C) and sudden drafts is advisable to prevent stress. This plant is adaptable to typical household humidity levels and does not require high humidity.
Fertilizing
Starfish Sansevieria is not a heavy feeder. During the growing season (typically spring to early fall), it can benefit from a balanced, water-soluble fertilizer diluted to half strength. Fertilize every four to six weeks, avoiding feeding during the plant’s dormant winter period. Over-fertilizing can lead to a buildup of mineral salts, which may harm the plant.
Potting and Repotting
Repotting Starfish Sansevieria is typically necessary when the plant becomes root-bound, which usually occurs every two to three years. When selecting a new container, choose one that is only slightly larger than the previous pot and always ensure it has drainage holes to prevent water accumulation. Terracotta pots are often recommended due to their porosity, which helps the soil dry faster and provides stability for the top-heavy plant. When repotting, maintain the same soil level around the plant’s base to avoid rot.
Propagating Starfish Sansevieria
Propagating Starfish Sansevieria can be achieved through division or leaf cuttings. Division involves separating young “pups” that emerge from the base of the mother plant, or splitting the rhizomes, and transplanting them into new pots. For leaf cuttings, a section of a leaf can be cut, allowed to callus for a few days, and then placed in a moist, well-draining soil mix until roots develop. New growth may take several months to appear from leaf cuttings.
Common Problems and Solutions
Overwatering is a frequent issue for Starfish Sansevieria, often leading to root rot, characterized by mushy stems or yellowing leaves. If this occurs, allow the soil to dry completely; if damage is extensive, repotting with fresh soil and trimming affected roots may be necessary. Curling leaves can indicate a lack of water. Pests like spider mites and mealybugs can affect the plant, particularly in dry conditions; isolating the plant and treating with neem oil can help manage infestations.
Safety and Placement Considerations
Starfish Sansevieria is considered mildly toxic if ingested by humans or pets, containing saponins that can cause gastrointestinal discomfort. Symptoms may include nausea, vomiting, or diarrhea. Therefore, place the plant out of reach of young children and pets. Considering its light preferences, ideal placement is in a bright room with indirect sunlight, such as on a desk or shelf.
