Tillandsia, also known as air plants, are a type of evergreen and there are hundreds of different species. They're quite cool as they suck in moisture and nutrients in the air through their leaves and not their roots, hence their alternate name of "air plants." Their roots are used as anchors only and they attach themselves to other plants. They're not parasitic though! They just use the host plants as homes.
Air plants are relatively low-maintenance and they bud and produce "pups" so you can grow more and more plants. I've shared multiple plant-related posts on here, all of them easy to care for. My succulent terrarium is still thriving at my office (I'll have to remember to take a photo of it as it has grown quite a bit), the mini garden's doing all right, and my bunny cactus is looking great, all because they don't require much help. If I haven't made it clear in the past, my (indoor houseplant) green thumb is not v. green. However, my outdoor green thumb is pretty awesome, as evidenced by my garden last year. Oh my gosh, speaking of which, I can't wait to plan this year's garden! AH!
