Tillandsia or Airplants are a really interesting group of plants. They come in a variety of colours and sizes and require so little attention, they don't even need any soil!
The name Airplant is slightly misleading in that they are called so, not because they require only air to grow, but because they require no soil at all to grow. They do need to be misted with water or soaked for 5-10 minutes every week, especially if the air is dry, like in Summer or in a centrally heated home in the colder months.
Buy Tillandsia plant by itself, or in a hanging glass bowl.
