When placed in a bowl of water, the plant perks up within about four hours. Don’t leave it standing in water for more than a few days, as this will make it rot. Change the water daily, and give it rest periods without water.
Can also be grown like an “air plant”. The roots don’t need to attach to anything, so you can attach it to another plant’s stems or place it on the surface of a pot with pebbles. Mist it down from time to time to keep it looking fresh.
