Orchid 6One of the most well-known houseplants, Orchids are easily recognizable by their tall stem and pendulant flowers. Orchids are tropical plants that require regular watering and warmer temperatures to thrive. Make sure that your pot has holes in the bottom for drainage; you don’t want to cause the roots to rot from sitting in water! Place your Orchid in a bright location and don’t movie it; it likes to be somewhat ignored. There are many varieties of Orchid to choose from, all of which are stunning.
