Selaginella uncinata or peacock fern is also known as rainbow moss for its beautiful blue-green lacy foliage. A tropical plant for lower light locations, terrariums and hanging baskets. Place in a warm spot with high humidity, mist the foliage regularly or set near a humidifier. Keep the soil moist but well-draining and let the water set out overnight to come to room temperature before watering. The foliage has an iridescent appearance depending on light, growing season and nutrition. Pet friendly!
