Fittonia, also known as Mosaic Plant, is an ornamental indoor plant admired for its variegated foliage, characterized by deep veining. The leaves, with variegated colors such as white, pink, red and yellow, are the main attraction of this evergreen perennial. With a creeping habit and the ability to send out roots at the nodes, the Fittonia does not exceed 30 cm in height but expands laterally.
In Italy, Fittonia is grown as an indoor plant, appreciated for its adaptability to small spaces. During flowering, it produces flowers that bloom between the bracts, creating spike-shaped inflorescences. An ideal choice for those looking for a decorative and easy to maintain plant in the home environment.
Origins
The Fittonia genus is part of the Acantaceae family, included in the Acanthoideae subfamily and in the Justicieae tribe.
In the same Acantaceae family we also find other famous genera, such as Thunbergia and Hypoestes phyllostachya, together with the renowned Acanthus, which won the hearts of classical artists.
Fittonias kept indoors rarely produce small flowers, which are generally eliminated to promote the health and beauty of the foliage. These flowers, which occur only occasionally in domestic environments, are grouped in spike inflorescences.
Variety
The most widespread Fittonia varieties suitable for growing in apartments include Fittonia argyroneura and Fittonia verschaffeltii, also known as Fittonia albivenis. These species are widely prized for their beauty and their ability to adapt to indoor conditions.

Fittonia argyroneura is characterized by dark green leaves with white or silver veins, which give the plant a distinctive and decorative appearance.
Fittonia verschaffeltii, on the other hand, has smaller and rounded leaves, with a variety of colors ranging from green to red and white, creating an interesting visual effect.
Both varieties are prized for their hardiness and their ability to survive in indirect or semi-shaded light conditions, making them ideal for indoor environments. However, it is important to maintain an adequate level of humidity around Fittonia plants, as they come from tropical environments and prefer a humid climate.
How to grow Fittonia
The cultivation of Fittonia can present challenges related to the creation of a humid environment, without however incurring water stagnation, which is essential for its growth.
However, commercially available cultivars are less demanding and more adaptable to the home environment, making indoor cultivation more accessible.
To successfully grow it in a pot, it is important to provide filtered sunlight and keep it in a warm environment. In addition, the humidity must be constantly high. Given the nature of its shallow roots, it is advisable to use shallow bowls rather than large pots.
To maintain humidity, you can opt for a deep saucer filled with expanded clay, kept constantly humid. Another option is to grow it in hydroculture. Alternatively, it can be grown in a bottle garden or terrarium, where humidity is always high.
If purchased in small pots, it is ideal for low compositions next to other plants of the same species but with different foliage. For larger plants, hanging containers or bowls with pebbles and decorative gravel are perfect.
Repotting is carried out in spring every 2-3 years, using wider and lower containers, with a soil composed of leaf earth and peat or universal soil and river sand, always guaranteeing perfect drainage.
What is the ideal temperature for Fittonia
Fittonia thrives best at an ideal temperature around 18°C, however, it tolerates temperatures between 20 and 28°C well. During the warmer months, from May to September, it can be placed outside in a shaded place. During the winter, however, it is advisable to keep it inside the house, away from heat sources and away from cold air currents, in a moderately bright environment.
Where to place the Fittonia
Fittonia does not require much light, but it is important to guarantee adequate exposure, preferably shaded or semi-shaded, without direct sunlight. Even if it is not particularly demanding, make sure that the environment in which it is located has good diffusion of light.
How and how much to water Fittonia
Fittonia requires regular watering, at least two to three times a week during the summer and reduced to once a week in the winter. It is important to prevent the soil from drying out too much between waterings, but also to avoid water stagnation.
How to multiply Fittonia
For the multiplication of Fittonia, which ages rapidly, it is advisable to proceed regularly. It can be multiplied by cutting or by dividing the stem.
Multiplication by cuttings
- Cut branch cuttings under the fourth pair of leaves, about 10-15 cm long, removing the two lowest leaves.
- Insert the cutting into the soil up to the height of the cut leaves, supporting it with a wire and gently compacting the soil around it.
- Place the vase in a dimly lit area at a constant temperature of approximately 21°C.
- Cover the pot with clear plastic to maintain heat and humidity.
- Every day, check the moisture of the soil and remove condensation from the plastic.
- When the cutting has rooted and new shoots appear, permanently remove the plastic cover and water regularly.
- Once the shoots are well developed, transplant them into the final pot in groups of 5-6 seedlings and treat them like adult plants.
Division of the stem
Fittonia can be easily multiplied by dividing the stem, as it produces roots at the height of the stem nodes.
Procedure:
- During spring, cut a part of the stem that contains the roots.
- Plant this portion of the stem in a suitable substrate, as described for adult plants.
- Place the seedling in a dimly lit area, maintaining a temperature around 21°C and ensuring that the substrate remains constantly moist.
- The new leaves will begin to develop and, once strengthened, the seedling can be treated like an adult plant.
Parasites and diseases
Aphids can infest stems and leaves, causing the plant to deteriorate, making it sticky and sooty. These parasites require specific treatments to fight. Excessive watering can lead to yellowing of the leaves.
Leaf fall and poor growth can be caused by placing the plant in a place that is too cold, it is advisable to keep it in a warm environment protected from drafts.
Problems common to Fittonia

Fittonies, with their elegance, may encounter some problems to consider to ensure their well-being.
Yellow leaves often indicate excessive watering, when the soil remains constantly moist, the roots can suffer from rot and show signs of stress through yellowing of the leaves.
Leaf fall can be caused by low temperatures or exposure to air currents, these plants in fact prefer a warm and protected environment, therefore, prolonged exposure to cold or air currents can weaken them and cause leaf fall.
Dry, shriveled leaves often indicate an environment with low humidity or strong exposure to direct sun. Fittonias love humidity and diffused light, but a lack of humidity or direct exposure to the sun can cause drying and wrinkling of the leaves.
Finally, infestation by insects such as midges and aphids can damage Fittonia, compromising their health. It is important to carefully monitor the presence of insects and adopt preventive measures or specific treatments to protect the plant from these parasites.
Is fittonia toxic?
Fittonia is considered a non-toxic plant to humans, dogs and cats, making it a safe choice for home environments with small children or pets. It is not included in the list of dangerous plants drawn up by the main international veterinary organisations. However, as with any ornamental plant, it is good practice to avoid ingesting the leaves, which could still cause mild gastrointestinal disorders in particularly sensitive individuals.
How to fertilize fittonia
During the vegetative period, from March to September, Fittonia benefits from regular fertilization every two weeks with a balanced liquid fertilizer, preferably low in nitrogen so as not to stimulate excessive growth to the detriment of the colorful foliage. In autumn the administrations must be gradually reduced, while in winter fertilization is suspended completely, as the plant slows down its metabolism and an excess of nutrients in this phase could damage the roots.
How to prune fittonia
Fittonia does not require drastic pruning, but regular intervention is useful to keep it compact and favor a dense and luxuriant growth. It is sufficient to periodically remove the longest and woodiest branches, cutting just above a node with clean, sharp scissors. This operation, ideal in spring, stimulates the plant to produce new lateral shoots, making it denser. The eliminated twigs, if in good condition, can be reused directly as cuttings for multiplication.
Curiosity
Native to South America, especially Peru, Fittonia was introduced to Europe in 1867 and takes its name from two English sisters, Elizabeth and Sara Fitton, authors of the book “Conversation on Botany” from the first half of the nineteenth century.
