Pink fittonia, the nerve plant, is a small houseplant with deep green oval leaves overlaid by a web of bright pink veins, an intricate pattern that reads like stained glass up close. It stays low and compact, which makes it a natural for terrariums, small pots, and mixed planters.

Give it bright, indirect light and keep the soil evenly moist; it wilts theatrically when thirsty and perks right back up after a drink. It loves humidity, so a terrarium, bathroom window, or pebble tray suits it well. Keep it warm and out of drafts.
