Selaginella Erythropus

A Crimson Shadow from the Jungle Floor

Step into a world of dramatic contrasts with the Selaginella erythropus, a rare and mesmerizing "spikemoss" that brings a fiery, gothic elegance to the botanical world. At first glance, this prehistoric treasure appears as a lush, fan-shaped canopy of deep emerald green; however, a subtle shift in perspective reveals its true secret—a brilliant, ruby-red underside that glows with an intense, sunset-like radiance. This "bicolor" phenomenon creates a stunning visual depth, where the cool green of the forest meets a warm, hidden fire. Compact, intricate, and undeniably exotic, it is a must-have for the collector who prizes texture and a sophisticated, moody palette.

Beyond its striking appearance, the Red-Stemmed Selaginella is a masterpiece of prehistoric design, perfectly suited for the intimate setting of a misty terrarium or a shaded plant gallery. Its fern-like, feathery fronds and vibrant crimson stems provide a unique architectural texture that thrives in the humid undergrowth. For the enthusiast seeking a specimen that feels like a living relic from a lost world, this variety offers an exclusive opportunity to own a plant that balances ancient resilience with a modern, high-contrast charm. Invite the Selaginella erythropus into your sanctuary and let its ruby-backed leaves transform your collection into a gallery of refined, tropical mystery.

• Growth Habit: A petite and enchanting perennial that exhibits a distinct, upright-clumping habit. Unlike creeping varieties, the erythropus grows in elegant, fan-like fronds that rise from the soil on vivid red stems. It stays relatively low and compact, making it a premier choice for adding vertical texture to the mid-ground of a terrarium or as a vibrant centerpiece in a glass cloche.

• Exotic Foliage: This species is celebrated for its dramatic color contrast. The tops of its lace-like fronds are a deep, satiny forest green, while the undersides and stems are saturated with a rich, oxblood or ruby-red pigment. This coloration is an adaptation to capture low-intensity light on the forest floor, resulting in a plant that appears to "glow" when light hits it from behind or at an angle.

• Light & Color: To maintain the intensity of its crimson underside and the deep green of its canopy, this plant thrives in medium to bright, indirect light. While it is highly tolerant of shaded conditions, insufficient light may cause the red pigments to fade. Conversely, direct sunlight is its greatest enemy and will quickly shrivel the delicate, thin fronds and scorch its unique colors.

• Care & Maintenance: This is a high-humidity specialist that demands levels consistently above 70% to keep its foliage soft and vibrant. It is a "moisture-loving" species that prefers a substrate that is consistently damp but never waterlogged; it does not tolerate drying out even for short periods. It flourishes in a well-aerated, moisture-retentive medium like pure sphagnum moss or a peat-based terrarium mix. To keep the fronds pristine, use only distilled or rainwater, as mineral buildup from tap water can cause the leaf tips to brown.

• Safety Note: Like most members of the Selaginella family, the erythropus is generally considered non-toxic to cats and dogs. This makes it a perfect, worry-free choice for pet owners who appreciate rare, high-end botanical aesthetics. However, because of its fragile stems and extreme humidity requirements, it is best displayed in a glass enclosure to protect it from dry air and accidental physical contact.
