Good terrarium plants include the moon valley friendship plant, variegata plant and nerve plant. The variegated spider fern and starfish plant also work well with different types of terrariums.
The moon valley friendship plant grows fast and does well with even low light. It reaches about a foot tall, so it is good with moderately sized terrariums. It also has pink flower blooms. Another plant that is approximately the same size is the nerve plant. This is more of a tropical terrarium plant, offering green and burgundy leaves. This plant grows best in humid environments. The variegata is good for smaller terrariums, reaching about 6 inches in height.
