Tillandsia ionantha is part of the Bromeliaceae family and its native range is Mexico to Central America. It is an epiphyte or lithophyte, growing primarily in the seasonally dry tropical biome. Leaf colouration is a beautiful silvery green with the centre becoming bright red when the plant blooms - this is to attract hummingbird pollinators - the flower is a violet colour.
The genus name was given by Carl Linnaeus to honour the Swedish physician and botanist Elias Tillandz (originally Tillander). Specific epithet is derived from the Greek, ion (violet) and anthos (flower).
Light: This plant loves bright, filtered light. In the UK, a spot near a south or east-facing window is perfect, provided it is shielded from the harshest afternoon sun in mid-summer. Inadequate light will prevent the plant from changing colour or producing flowers.
Water: Since it lacks soil, this plant absorbs moisture through its leaves. The most effective method in a home is to submerge the entire plant in a bowl of rainwater or filtered water for about 20 to 30 minutes once a week. Afterward, it is vital to shake off any excess water and let it dry upside down for a few hours to prevent rot in the base. Occasional misting between soaks can be helpful in centrally heated rooms.
Soil: No soil is required. In fact, planting it in traditional potting mix will cause it to perish. It can be displayed in glass terrariums, mounted on wood, or simply placed in decorative bowls.
Fertilising: Use a specific bromeliad or air plant fertiliser at a quarter-strength once a month during the spring and summer. This can be added to your soaking water or sprayed onto the leaves.
Temperature: It thrives in average household temperatures, typically between 15°C and 27°C. It should be kept away from freezing temperatures and cold window draughts during the winter months.
Humidity: Good airflow is just as important as humidity for this species. It enjoys a humid environment but must be allowed to dry out completely between waterings to stay healthy.
Growth Habit: It grows in a small, clumping rosette. After flowering, the mother plant will produce offsets at its base. These can be left to grow into a large cluster or carefully removed once they reach about a third of the parent's size.
Toxicity: Tillandsia ionantha is considered non-toxic to both humans and pets, making it a safe choice for households with curious cats or dogs.
