Tillandsia (Air Plant)
Tillandsia spp.
A fascinating genus of over 650 species in the Bromeliaceae family, native to the diverse climates of the Americas. As epiphytes, these unique plants do not require soil to grow, instead clinging to trees or rocks in the wild. They utilize specialized silver scales on their leaves called trichomes to absorb moisture and nutrients directly from the air and rainfall, making them a marvel of botanical adaptation.

Care Guide
Watering Protocol
Soak your Tillandsia in a bowl of room-temperature water for 20-30 minutes once a week.
Crucial: After soaking, shake off all excess water and place the plant upside down on a clean towel in a well-ventilated area. It must dry completely within 4 hours to prevent crown rot.
Light and Airflow
Place in a spot with bright, filtered sunlight. Avoid direct afternoon sun which can dehydrate and burn the leaves. Good air circulation is vital; do not keep them in enclosed terrariums for long periods without ventilation.
Temperature
Keep your air plants in temperatures between 50°F and 90°F. They are not frost-tolerant and should be moved away from drafty windows during winter months.
Common Issues
Brown, crispy tips: Indicates underwatering or low humidity.
Black or soggy base: Indicates rot from trapped water. Immediately remove affected leaves and ensure better drying practices.
