The Frosty Fern, scientifically known as Selaginella kraussiana 'Frosty', is a decorative and resilient plant often utilized as ground cover or in hanging baskets. Its delicate, feathery foliage features a silvery-blue hue, giving it a frosty appearance, hence the name. Frosty Ferns are low-maintenance and thrive in indirect light with consistently moist soil.
