Small tropical plant sizes range from twelve inches to four feet, and small plants are typically grouped together to present a stronger impression than a single small floor plant alone. Plant container selection is unlimited, and the small floor plants can be placed in a raised planter or in a container with a stand to enlarge the appearance of the tropical plant. Small plants can be used as under plantings to exhibit larger floor plants, and indoor plants add a highlight of neon green or contrasting bright colors to a green landscape.
