Tillandsias, also known as air plants, are excellent for growing in pots in cold regions such as USDA Zone 8-11. They can be cold hardy at least to 30s F for a short time, and come in many different varieties that can grow to different heights, depending on the species. Some prefer semi-shade and others require more direct sunlight.
Tillandsias are known for being the world's most unusual airplants, and are a delightful addition to any greenhouse. They are easy to care for, exotic to look at, and interesting to study. Unlike other bromeliads, Tillandsias are air plants, much like vandaceous orchids. They have developed the ability to take all their food and water through specially designed cells on their leaves, and can therefore exist without any roots.
While roots are used by most species to attach themselves, Tillandsias can grow in places no other plants can survive, including on electrical cables on power lines. They prefer light airy conditions and daily misting in areas of low humidity. They must be brought into protection from any freeze, but a light frost will not usually damage them. The greener and softer varieties like a little more water and shade. Any can be grown in your sunniest indoor area.
All Tillandsia plants require regular misting waterings and offer a range of vibrant color displays. Pink, white, off-white, red, crimson, vinous, yellow, and orange flowers can be seen on some of the varieties. Proper growing and plant care can ensure that your Tillandsia will thrive and offer a beautiful, long-lasting display of foliage and flowers for years to come.
Enjoy your Tillandsia plant for years of blooming and pupping with good light, fresh air, and adequate but not overabundant watering, particularly in cooler weather.
