Tillandsia caput-medusae

Where Tillandsia caput-medusae grows naturally

Tillandsia caput-medusae is native from Mexico through Central America. It grows attached to trees and other exposed supports without soil in seasonally dry tropical habitats.

Its natural habitat has distinct wet and dry periods. Rain and moisture from the air wet the plant, while its exposed position allows it to dry quickly afterwards.

Indoor care for Tillandsia caput-medusae

• Drying: Shake out the plant after watering and turn it upside down or on its side until trapped droplets have drained from the swollen base.
• Water: Wet the whole plant thoroughly, then allow it to dry before the next watering. Do not keep the rosette continuously damp.
• Airflow: Keep air moving freely around the base and leaves, especially after soaking or rinsing.
• Light: Provide bright, filtered light and introduce direct sun gradually. Hot glass can still scorch the leaves.
• Humidity: Moderate humidity is sufficient in most homes if you adjust watering to how quickly the plant dries. If humidity is high, make sure air can still move around the plant.
• Display: Grow without potting soil on an open stand, piece of wood or other dry support. Do not pack material that stays damp around the swollen base.
• Temperature: Keep it warm. Around 12 °C or lower, avoid soaking the plant because the swollen base will dry much more slowly.
• Feeding: Add a very dilute orchid or bromeliad feed occasionally to the water when you water the plant. Avoid strong fertiliser on the leaves.
• After flowering: Once this rosette has flowered, it gradually declines as new pups take over. Keep the mother attached until it has dried completely before removing it.
• Offsets: Leave pups attached for a fuller cluster, or wait until they have reached roughly one-third of the parent’s size before separating them.

Tillandsia caput-medusae problems and solutions

• The base becomes soft, dark or foul-smelling: Water has remained trapped around the leaf bases. Stop watering until the plant is dry, improve airflow and remove only clearly rotten tissue with a disinfected tool, discarding everything removed.
• Leaves curl much more tightly than normal and the tips turn brittle: The plant is too dry; some twisting is natural, so look for a clear change from its usual shape. Give it a thorough soak or rinse and water a little sooner.
• Flat pale or brown patches appear: Sudden strong sun or overheating has scorched the exposed leaf surface. Move it away from hot direct sun and increase exposure gradually.
• Cottony spots or small hard bumps appear between the leaves and do not brush off: Inspect for mealybugs or scale. Isolate the plant and remove a small infestation carefully; if treatment is needed, use only a product labelled for the identified pest and ornamental houseplants and repeat treatment only as often as the label says.

If the problem is unclear or continues to worsen after the likely cause is corrected, send us clear photos of the whole plant and the affected area so we can help identify it.

Tillandsia caput-medusae is non-toxic to people and pets

• This plant is non-toxic to people, cats and dogs.
• Chewing a large amount can still cause an upset stomach.
• If a large amount is eaten and symptoms continue, contact a veterinarian or medical professional.

How the name Tillandsia caput-medusae came about

Tillandsia honours the Finnish physician and botanist Elias Tillandz. The epithet caput-medusae is Latin for Medusa's head, referring to the twisting leaves.

Carl Linnaeus established the genus Tillandsia in 1753 in Species Plantarum, page 286.

Charles Jacques Édouard Morren first described Tillandsia caput-medusae in 1880 in Annales de Botanique et d’Horticulture, volume 30, page 90.
