The Fittonia, also known as the Nerve Plant or Mosaic Plant, is one of the most popular terrarium plants in the world. With its striking network of coloured veins against lush green leaves, it creates instant impact in even the smallest of spaces. Compact, easy to care for, and perfectly adapted to humid environments, Fittonia is widely considered the best plant for terrariums. At around 12-14cm tall in an 12cm nursery pot, Fittonia is the ideal choice for bottle gardens, closed terrariums, or for adding a splash of colour to a bathroom or kitchen shelf. Its low-growing, spreading habit makes it perfect for filling gaps, adding texture, and bringing detail to plant displays. Native habitat and growthFittonia is native to the tropical rainforests of South America, where it grows along the forest floor in warm, shaded, and humid conditions. Indoors, it thrives when given the same environment, making terrariums the easiest and most reliable way to keep it happy.
