Gasteria sp. 'Cow's Tongue' (Isomatsu)



This RARE variety Gasteria plants typically feature rosettes of thick, tongue-shaped leaves that resemble a cows tongue. They are known for their ornamental value, often resembling aloe plants but with distinctive leaf patterns and textures.



Gasteria species are native to Southern Africa, particularly in regions with dry, rocky habitats where they grow in well-draining soils.


Care Sheet:

  • Light:

    • Requirement: Bright, indirect light.
    • Details: Gasteria prefers bright, indirect light. They can tolerate some morning or evening sun but should be protected from intense afternoon sunlight, which can scorch their leaves.
  • Watering:

    • Requirement: Moderate watering.
    • Details: Water thoroughly when the top inch of soil feels dry during the active growing season (spring and summer). Allow the soil to dry out between waterings to prevent root rot. Reduce watering in winter when growth slows down.
  • Soil:

    • Requirement: Well-draining soil.
    • Details: Plant Gasteria in a well-draining succulent or cactus mix. You can also create your own mix using equal parts of potting soil, sand, and perlite to ensure good drainage.
  • Temperature:

    • Requirement: Moderate temperatures.
    • Details: Ideal temperatures range from 65°F to 75°F (18°C to 24°C). Protect Gasteria from temperatures below 50°F (10°C), as they are sensitive to cold and frost.
  • Humidity:

    • Requirement: Low to moderate humidity.
    • Details: Gasteria plants prefer average humidity levels and do not require additional humidity. Good air circulation helps prevent fungal diseases.
  • Fertilizing:

    • Requirement: Light fertilization.
    • Details: Fertilize sparingly with a balanced fertilizer diluted to half-strength during the growing season (spring and summer). Avoid fertilizing during the winter months.
  • Repotting:

    • Requirement: Infrequent repotting.
    • Details: Repot Gasteria plants every few years or when they have outgrown their containers. Choose a slightly larger pot with drainage holes to accommodate their root system.
  • Propagation:

    • Requirement: Offsets or leaf cuttings.
    • Details: Propagate Gasteria by dividing offsets (pups) that grow around the base of the mother plant. Allow the offsets to dry and callous before planting them in a well-draining soil mix. Leaf cuttings can also be propagated similarly.


By following these care guidelines, you can successfully cultivate Gasteria sp. 'Cow's Tongue' or similar varieties, appreciating their unique foliage and easy-going nature in your collection of succulents. If you have a specific variety or cultivar in mind, adjusting care based on its specific traits may be necessary.
