For the busy gardener, an indoor garden provides an easy, convenient and low-maintenance way to grow some plants. For the ambitious decorator, indoor plants provide a great way to add some color and vibrancy to the house. For the rest of us, an indoor plant garden provides a way to keep plants growing through the darkest months of winter.
Small cacti are popular indoor garden plants. Grow them individually, or grouped in a cactus garden as part of a miniature desert landscape. Cactii prefer lots of bright light, and should be given southern or western windows if possible. They will survive pretty much anything but overabundance. Allow the soil to dry between waterings. In the winter, only water your cactus monthly, but in the summer you can water it every time the soil gets completely dry.
If you like to cook, an indoor herb garden is an extremely rewarding thing to have. You can grow your indoor garden plants on the windowsill and plant it with basil, thyme, sage, dill, mint, and any other herbs you cook with regularly. You can pick a few leaves or sprigs from your indoor herb garden any time you want to add a dash of flavor to a meal. Alternately, dry herbs from your indoor herb garden ahead of time, crumble them and mix them into your favorite spice blend.
All plants absorb carbon dioxide and release oxygen, but some species are especially adept at cleaning the air. Spider plants, English ivy, peace lily and several other species of indoor plants are quite efficient at reducing or removing benzene, formaldehyde and other common indoor pollutants from the air.
