Tillandsia
Plants that survive and grow without having to be placed in any medium (soil, moss etc.)
They are epiphytes and grow in nature on the trunks of trees
Give them a good soaking for about 1hr every 1.5 weeks, shake off excess water and place in a brightly lit area of your home or office.
They look great placed around the home solo or in cute decoratative planters, glass orbs etc.
