Tillandsia melanocrater has been reclassified to Tillandsia tricolor. It is part of the Bromeliaceae family and its native range is S. Mexico to Central America where it grows as an epiphyte primarily in the wet tropical biome.
This Tillandsia is more tolerant to less airflow than silvery species and it will turn red if exposed to higher light levels.
The genus name was given by Carl Linnaeus to honour the Swedish physician and botanist Elias Tillandz (originally Tillander). The specific epithet is derived from Greek, meaning "dark crater" or "black cup".
Light: This species prefers bright, indirect light. In the UK, it does well on a bright windowsill that avoids the scorching midday sun. Because its leaves are more rigid and waxy than other air plants, it can tolerate slightly higher light levels, but it should still be protected from extreme heat behind glass.
Water: As an epiphyte, it takes in water through its leaves. A weekly soak in rainwater or pond water for around 15 to 30 minutes is ideal. Because this plant has a tighter, more upright rosette, it is especially important to turn it upside down and shake it thoroughly after watering to ensure no liquid remains trapped in the central "cup," which can lead to rot.
Soil: This plant must not be planted in soil. It is best displayed by mounting it onto cork bark or stone, or simply placed inside a decorative wire holder or aerated glass vessel where air can circulate freely around the base.
Fertilising: To encourage growth and flowering, you can use a specialist air plant or bromeliad fertiliser once a month during the spring and summer. Use a very weak dilution and mist it onto the foliage.
Temperature: It thrives in standard UK indoor temperatures, generally between 10°C and 25°C. Ideal temperature range 18-30˚C. It is important to keep it away from radiators during the winter, as the dry heat can cause the leaf tips to turn brown and brittle.
Humidity: Tillandsia melanocrater enjoys a humid atmosphere. Regular misting between soaks is beneficial, particularly in the winter when central heating tends to dry out the air in British homes.
Growth Habit: It grows in an upright, fountain-like shape. Once the plant has finished flowering, it will gradually produce small offsets at the base. These can be left to form a multi-plant cluster or detached once they are large enough to survive on their own.
Toxicity: This plant is non-toxic to humans, cats, and dogs, making it a worry-free addition to a pet-friendly home.
