A green or flowering potted indoor plant will add instant warmth and decor to a new home, regardless of the new homeowners decorating style. Fans of feng shui design will love the serene look of a zen orchid plant, they are stunning as an entryway piece and evoke a sense of peacefulness in the home. Or send a cheerful bouquet right after the homeowners move in. It will give them a pretty focal point and help make them feel right at home in their new surroundings, which is likely still filled with boxes and moving supplies. Even if a family member or friend has moved far away, a thoughtful housewarming gift will remind them that though they may be out of sight, they are not out of mind.
