Fittonia are spreading evergreen perennials growing 10–15 cm (4–6 in) tall. Sporting dark green leaves with veins of white. Its spreading habit makes it ideal as groundcover. It is not frost hardy therefore best grown in a greenhouse or as a houseplant. Without water for a few days, this plant will "faint" but is easily revived with a quick watering. 'Frankie' has pink leaves with frilly, green edges. Quite stiff leaves when watered well.
