Considered non-toxic to cats and dogs (source: ASPCA (not specifically listed; treated pet-safe)).
A sunny south-facing window with 6+ hours, or a grow light.
Keep evenly moist — water when the top inch of soil is dry.
Needs a little consistency, but nothing fancy.
Air plants are small rootless bromeliads that grow without soil, absorbing water and nutrients through their leaves. They are generally pet-safe and need no pot, but they do need regular soaking, not just misting.
About Air Plant
Air plants (Tillandsia ionantha) are small, rootless bromeliads from Central America that grow without soil, drawing water and nutrients in through their silvery leaves. Each rosette is only 5 to 10 centimetres and needs no pot at all, so it can sit in a dish or be mounted on almost anything. For a renter, that no-soil, no-pot quality makes it about the most flexible plant going.
The catch is watering: it needs a real soak rather than a quick misting. Soak it in water for 20 to 30 minutes about weekly, then shake it out and dry it fully upside down so no water sits in the centre. Give it bright indirect light, since with no roots, light and the soak are everything. The species isn't specifically listed by the ASPCA and is treated as pet-safe.
What it’s like to grow
Air plants are moderately fussy in an unusual way, because all the care happens through the leaves. Rot in the centre is the classic mistake, caused by water left sitting after a soak, so drying it upside down matters as much as the soak itself. Dry, curling, crispy tips mean it isn't getting enough water and needs longer or more frequent soaking. Worth it if you'll commit to a weekly routine. Not specifically listed by the ASPCA and treated as pet-safe.
What to expect
It asks for a little consistency, but nothing fancy. No sunny window? It also does fine under a clip-on grow light.
