It's still too early to head out and plant anything outdoors for spring, but with Smith & Hawken's Large Cloche with Saucer, you can get your seedling off to a good start in the comfort of your own home. The miniature terrarium is ideal for starting seedling when the weather outdoors is less-than-ideal. The mouth-blown glass bell keeps the soil warm and moist, as well as creating a visually pleasing display for the plants it contains. It measures 13 3/4" x 13 1/4". Price: $70.

If you don't have a "green thumb," maintaining any type of plant life in the house can be difficult, but instead of hiring a gardener for your indoor plants or switching to artificial flowers, you can install a plantwall. The Plantwall is a vertical pant installation that is "almost like being outside inside." It has an integrated irrigation system that distributes water and fertilizer throughout the wall, so there should be no reason for the wall to be anything other than lush and green. The price depends on the size and shape of the wall you want, as well as on the type of plants that you want to showcase.

The AeroGrow AeroGarden is a self-watering, self-feeding planter that lets you garden from the comfort of your kitchen without actually having to do anything. Tested by NASA, the planter uses "aeroponic technology," which means that the plants are suspended in a non-soil environment with 100% humidity, similar to an optimal rainforest climate. This enables plants to grow up to 5 times as fast as they normally would and, since no human intervention is required, the plants are guaranteed to thrive.

The built-in lights simulate a full spectrum of daylight lighting, so no natural sunlight is actually needed, and a computerized alarm system reminds you to check in on the plants. It includes a salad greens kit, but seed kits for herbs, tomatoes, flowers and chili peppers can also be purchased. Check out the FAQ for more info. Price: $199.
