Red fittonia, the nerve plant, has deep green leaves veined in bright red, a netted pattern so precise it looks drawn on. Staying small and low, it is a favorite for terrariums, small pots, and the front of mixed planters where the detail can be admired up close.

Keep the soil evenly moist and the humidity high; a terrarium, bathroom, or pebble tray suits it well. Bright, indirect light preserves the red veining. If it wilts dramatically from thirst, water promptly and it usually rebounds within hours. Average room warmth, no drafts.
