Branch Home has these teeny (3.5 inch diameter) indoor gardens that you can literally start on a desktop.
Made in Japan, these tiny aluminum tins hold black sand soil and seeds. Open, water, enjoy! When your plant grows up, move to a large pot or outdoors proudly.
Available in Clover (above), Bonsai, Christmas Tree, Prairie, and Cactus for $12.
The Egg plants work much the same way. The pre-seeded soil is sealed inside the unglazed ceramic egg. Tap gently to break the top and you are on your way to an herb garden. Available in Thyme (right), Lemon Balm, Mint, Chamomile, Parsley and Basil for $14.
