Roses, trees, tulips, and shrubs are some of the best ornamental plants for decorating a home. Roses come in many colors and can give a landscape look. Popular ornamental trees include apple, pear, cherry, junipers and cedars. Tulips bloom in the spring but must be stored over winter as they are not cold-weather plants. Shrubs like barberry and camellia have nice blooms and smells despite their smaller size. Using these ornamental plants can give a home a new and attractive look.
