Air plants, also known as epiphytes, are plants that do not require soil to grow. Instead, they obtain their nutrients and moisture from the air and rainfall. They are native to rainforests, deserts, and other dry areas throughout the world. Some common types of air plants include Spanish moss, tillandsia, and bromeliads. They vary in size and appearance, with some growing very small and others growing several feet long. Many have unique, delicate flowers that bloom in vibrant colors. Air plants can be displayed in a variety of creative ways, such as in hanging terrariums, mounted on walls or driftwood, or even in glass globes. They require minimal care, but need to be misted or soaked in water every one to two weeks to stay healthy.
