Wimpy Houseplants

Sure it's fine to show off your green thumb inside the house. Just don't scatter too many small houseplants around the room. They'll have much more effect if you bank three to five small plants together. For example, poinsettias, classics of the holiday season, look stunning in a mass grouping. Or, buy one large-scale plant that makes a bold statement (and doesn't have to be watered as often).
