This page covers what makes blushing air plant different. For light, water, soil, pests, and the rest, read the air plant care guide.
What it is
Tillandsia ionantha is the most common air plant. It is small, about the size of a walnut, with stiff, silvery-green, pointed leaves in a tight rosette. Before it blooms, the inner leaves blush bright red or pink. Then a purple flower pokes out of the center.
How to tell it apart
| Plant | Leaves | The tell |
|---|---|---|
| Ionantha | Small, stiff, silver-green, tight | Small and blushes red |
| Xerographica | Large, curling, silver | Much bigger, with curling leaves |
| Spanish moss | Thin, hanging strands | Long gray strands, no rosette |
Care differences
Care is the same as the hub. Its small size means it dries fast. Soak it every week in warm months.
After it blooms
It blooms once, then makes pups at the base. Leave the pups on to grow a clump, or twist them off once they are one third the size of the mother.
Buying it
Ionantha is sold everywhere. Look for firm, plump leaves. A soft, brown center means rot.
