It is a species native to Central America, especially Nicaragua and Guatemala, which grows in tropical and subtropical regions, where the humidity is relatively high and light is abundant. Being a planted air, does not require a substrate to live, since It obtains water and nutrients from the air through its trichomes, small specialized structures in their leaves.
Its appearance is compact and decorative, as it generally presents a small size, between 5 and 10 centimeters high and a similar diameter. Their The leaves are elongated, thick, pointed and arranged in a rosette shape., which allows the plant to retain moisture and make the most of ambient light.
For most of the year, the leaves show a grayish green or silvery green color, but one of the biggest attractions of ionantha rubra is the transformation they undergo during flowering: its central leaves acquire tones pink, red or even orange under high light conditions. During this period they appear in the center small tubular flowers of deep violet or purple-blue color, with yellow stamens, which offer a fascinating contrast. This flowering period is brief but truly spectacular, which is one of the reasons why this tillandsia is so popular in plant decoration.
The Ionantha rubra has semi-succulent leaves This allows it to store water, efficiently adapting to periods of drought. The rounded shape and density of the rosette make it versatile for placing on logs, stones, wood, glass bells, or any decorative support without the need for a pot, making it easy to combine it in vertical gardens, terrariums, or living paintings.

For example, 'Ionantha druid' is characterized by its white flower and yellow central leaves during flowering, making it a rare albino specimen. Although each variety can present different shades depending on the season and life cycle, the rubra is appreciated precisely for the intensity of its reddish tones during flowering and its ease of maintenance.

The reddish hue is a signal that attracts natural pollinators, such as insects and hummingbirds, which are vital for the continuation of the species.
The term “ionantha” comes from Greek and means “with violet flowers”, referring to the bright color of its inflorescences.
