Many plants can be used indoors with favorable results as long as they are not labeled "full sun". These types of plants generally need more lighting than can be given indoors. Also choose plants that are labeled "partial shade" or "full shade", these will need much less lighting. Pick a container that is both proportional to your plant (no tiny plants in large planters or trees in tiny pots) and will complement your design taste.
