Terrariums, miniature gardens enclosed in glass, are bigger than ever in home decor. And the current crop of indoor displays for your house or office features an amazing selection of containers.

Everything from succulents to ferns and moss can be grown in these indoor gardens, which have been popular as far back as the 1800s. Elegant Victorian-style cases remain popular, but contemporary styles include delicate hanging orbs, handblown pitchers and simple jars.

Michler's Gardens and Greenhouses of Lexington, Ky., carries a variety of terrarium sizes.

"It really has a broad range," Robin Michler said. "Some are quite small and could fit in a nice window table, and others are completely self-standing and can sit on their own table."

West Elm, the furniture and home decor store, offers a selection of hanging glass bubbles designed by artist Shane Powers. Ranging from $9 to $34 at Westelm.com, they're affordable enough to hang in groups for an eye-catching display.

Better Homes & Gardens magazine devoted several pages to terrariums in its January issue, including tips from Tovah Martin, author of "The New Terrarium."

Martin suggests sticking to small plants and clear containers. Gather your favorite plants in your own piece of glass, or buy terrariums already assembled from an array of stores.

Ready-made designs at Etsy.com include apothecary-style jars filled with moss, pine cones and river stones from Doodle Bird Imaginariums. The tiniest of terrariums may be worn as necklaces or rings, and several online storefronts offer accents for your container, including mini ceramic mushrooms, deer and farm animals.
