Citrus trees also do well indoors, as long as they are provided with at least four hours of direct sunlight each day. A citrus tree can be kept in a breakfast room or on an enclosed porch with plenty of light, or it can be moved to take advantage of the sunshine.
One way to find suitable trees that may work for your indoor situation is to go to the produce section of your supermarket and buy some fruit; try guava, lemon, kumquat, tamarind, and fig. As you eat the fruits, save the seeds and plant them. Some of these will survive, and may make good plants for indoor bonsai. Next, go to your local plant nursery, and select any small-leaved tree from their terrarium selection. Trees that you can find are cotoneaster, chamaecyparis, boxwood, myrtle, elm, and ivy.
