Red vein tracery makes this fittonia a living map across dark leaves, a houseplant that draws the eye even when it's resting. It thrives in moderate warmth and wants soil that never fully dries out, which makes it happiest in a terrarium or grouped with other plants that appreciate the same attention.

Set it on a table away from heating vents and cold drafts, and mist occasionally if your indoor air runs dry. You'll see it flag a little when thirsty—that's your signal to water, and it bounces back within an hour.
