Fittonias, also known as the Nerve Plant, Mosaic Plant or Net Plant, are a genus of flowering plants in the Acanthaceae family native to the tropical rainforests of South America. A low-growing evergeen creeper, Fittonias can reach a height of 3 to 6 inches and spread across 12 to 18 inches, making these non-creepy, creepers an excellent house plant for small homes and terrariums. Did we mention they’re super vascular, bro? Their show-y foliage veins come in a number of different colours depending on the varietal, which is why these plants often receive top-billing in a terrarium. If he conditions are right, Fittonias will flower and bare its flower-y teeth with reddish or yellowish-white spikes – but it’s rare for that to happen. They’re a bit temperamental, but certainly worth the effort.
