Pond Plant Spotlight: Mosaic Plant

The mosaic plant is related to the genus Fittonia and is prized by many due to its stunning foliage and veins which are a combination of pink, white and red. The downside to this plant is that it can be tough to grow under normal room conditions, meaning it might not be the best pond plant for beginners. However, the many sustainable benefits it provides make it well worth the effort.


The Mosaic plant is perennial and can be added to ponds or used as a houseplant. It takes about three years to grow to maturity, and requires considerable warmth along with lots of moisture for its leaves. Aside from ponds, many homeowners like placing them in terrariums, and there is a dwarf variant that is much easier to handle than the standard species.

Botanists believe the plant originates in Peru which explains its need for warmth and moisture. Other Fittonia plants are native to the South American rainforests and they produce green leaves which are lush and have veins, which are artfully accented.

Physical Appearance

A bit of fuzz can also be seen on the stems. As the plants grow, miniature buds will appear as the stem divides into leaves. The flowers produced by this plant are relatively small, and if you intend to use these plants in a temperate climate then it is best to install them in an indoor rather than outdoor pond.

If the Mosaic plant is not sufficiently watered it will faint after a few days have passed, but it can be revived if watered in time. Within the USA, it will thrive in ponds located in subtropical and tropical climates (such as the American South and South Florida), but will be harder to manage in northern climates due to the colder winters. These plants reach a maximum height of about 5.94 inches and their maintenance requirements are moderate.

Growth Recommendations

To grow this plant, you must be prepared to put in the time and effort, or hire an expert who can. The compost has to be kept moist constantly yet should never become waterlogged. During winter watering should be reduced. You must also pay attention to the type of water you use (tepid and soft is best). Unlike other plants, it isn’t necessary to use misting.

You can tell when you’re overwatering Mosaic plants because their leaves will turn yellow. If the leaves begin to wither, this means you need to increase the humidity. The ends of the growing stems can be pinched so the plants can be shaped to promote foliage which is denser.  You want to water this plant frequently, and because it is considered to be half hardy, it must be protected from both frost and temperatures which are low.

When placing the seeds of this plant near your pond, create gaps of about 2 inches so that the seedlings do not become overcrowded. The most ideal temperatures for growth should be no lower than fifty five degrees Fahrenheit.
