Spray the leaves of your plant with rainwater immediately upon receipt. If you do not have any rainwater to hand place the pot under the tap and trickle some warm (room temperature) water over the plant, the water should not be cold.
Stand the whole arrangement in a warm, fairly light spot, but keep it away from direct sunlight. The lighter the spot, the longer the plant will stay red.

Tillandsia is an easy to grow houseplant requiring little or no maintenance. Spray the plant, preferably with rainwater at room temperature. In the summer it will appreciate being stood outside on the patio during a summer shower.
Feeding the plant is not strictly necessary but if you want it to grow bigger, would certainly help. A liquid feed is recommended in this case - just spray as watering. There is a special Tillandsia feed but you can also use standard houseplant fertiliser, diluted 1:4 with rainwater. A temperature of between 16° and 24°C is perfect for Tillandsia.
Tillandsia ionantha will turn a beautiful red colour just prior to flowering. The plant requires direct sunlight to flower again. It is a little more difficult to get other varieties to flower a second time.

Exceptional and unusual, Tillandsia can be found growing on the branches of giant trees in tropical rainforests. The high degree of humidity in the tropics is sufficient to keep the plant thriving - water and minerals are absorbed through the leaves of this pretty little plant.
Tillandsia roots are more for support than sustenance and are used to hold the plant to the tree. This lovely tillandsia can tolerate the dry air of our living rooms. Tillandsia and other bromeliads are often used in a terrarium or palludarium.
