The term greenery is generally used to describe the foliage of a plant, whether it is live or artificial. This may follow a literal interpretation and be taken to mean only green foliage. However, variegated foliage with other colors, inclusive of green, can be included in this definition. There is a large variety of silk greenery in existence today. They usually fall into the categories of silk bushes silk ferns, and silk garlands and swags.
