The terrarium trend keeps heating up, and we're all over it. This offering from our compadres at Sprout Home comes in recycled glass, which is free-blown into a bubble that's flattened and curved into a shape. Available in four sizes (small, medium, large, and extra large), each Recycled Glass Terrarium is totally unique. The terrariums arrive empty, so it's up to you to plant it up. Fern, cactus, moss, succulent -- take your pick, any appropriate terrarium plant will find a happy home.
