Tillandsia bulbosa

Tillandsia bulbosa in the wild

Tillandsia bulbosa has a broad native range across tropical America, from southern Mexico and the Caribbean through Central America into northern and eastern South America. It grows attached to branches without soil and is found mainly in wet tropical habitats.

Caring for Tillandsia bulbosa

• Water: Wet the whole plant thoroughly, then let it dry fully. Because it comes from wetter habitat, water again once it is dry and avoid leaving it dry for a long stretch.
• Drying: The swollen base can hold water. After watering, shake it well and turn it upside down or on its side until no water remains trapped between the overlapping leaf bases.
• Light: Bright, filtered light is ideal. Give some protection from harsh midday sun through glass, especially if the plant has been kept in lower light.
• Humidity: Moderate to high humidity suits its wetter natural habitat, provided the plant is never left damp in still air.
• Airflow: Keep it in an open, well-ventilated position. Good air movement is particularly important around the swollen base after watering.
• Temperature: Warm indoor conditions suit it. If the room approaches 12 °C, wait for warmer conditions before a thorough watering so the swollen base is not left cold and wet.
• Display: Grow it without potting soil on an open stand, branch or other support. Do not bury the swollen base in moss or another material that stays wet.
• Feeding: Add a very dilute orchid or bromeliad fertiliser to the water occasionally.
• After flowering: The mother rosette gradually declines after flowering while pups at the base continue growing. Leave the mother in place until it is fully dry, then remove it.
• Offsets: Leave pups attached for a fuller cluster, or separate them only after they are well established and roughly one-third the size of the parent.

Problems with Tillandsia bulbosa and what to do

• The swollen base turns black or soft: Water has probably remained trapped in the swollen base or the plant has stayed wet without enough airflow. Stop soaking until the plant has dried, remove only loose rotten tissue with a disinfected tool and discard it. If the centre of the plant is black and mushy, recovery is unlikely.
• Leaves lose firmness and look more shrivelled than usual: The plant is too dry. Give a thorough soak or rinse, then adjust watering so the leaves become firm again without leaving the base wet afterwards.
• Brown, dry tips spread further down the leaves: Repeated under-watering or very dry, hot air can contribute. Water more consistently and check whether hot, dry air is making the plant dry too quickly.
• Pale tan patches develop on the upper side of the leaves: The leaves have probably scorched after too much direct sun or heat. Move it away from hot glass and increase direct light only gradually.

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 bulbosa 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.

Tillandsia bulbosa: where the name comes from

Tillandsia honours the Finnish physician and botanist Elias Tillandz. The Latin epithet bulbosa means bulbous, referring to the swollen, bulb-like base.

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

William Jackson Hooker first described Tillandsia bulbosa in 1825 in Exotic Flora, plate 173.
