The Lazarus plant, Selaginella lepidophylla, is a captivating botanical specimen known for its ability to revive itself from extreme dehydration. Often called the “resurrection plant,” “rose of Jericho,” or “dinosaur plant,” it appears lifeless before unfurling into a vibrant, fern-like form upon contact with water. Originating in the arid Chihuahuan Desert, its survival mechanism allows it to withstand prolonged periods without moisture, returning to full metabolic activity even after losing nearly all its water.
Understanding the Lazarus Plant
The Lazarus plant’s appearance changes with hydration. When dormant and dry, it curls inward, forming a tight, leathery, dark brown ball resembling a dried tumbleweed. This state minimizes its surface area, conserving moisture. Upon rehydration, its stems and leaves gradually unfurl into a flat, spreading rosette of delicate, green foliage, typically reaching 5 cm. This spikemoss, a primitive vascular plant, reproduces through spores. It thrives in sandy, well-drained soils and open, sunlit desert habitats.
The plant’s “resurrection” is due to physiological processes protecting its cellular structures during desiccation. It can lose up to 95% of its moisture without permanent damage. This survival involves protective compounds like trehalose, a sugar that replaces evaporating water and stabilizes cellular structures. When water is available, these sugars dissolve, reactivating the plant’s metabolism and rehydrating its tissues.
Reviving Your Lazarus Plant
Reviving a dormant Lazarus plant is simple. Select a shallow, non-porous dish and place the dried plant into it. Use room-temperature water; distilled, rainwater, or dechlorinated tap water are suitable.
Pour water into the dish, ensuring the plant’s base is submerged and the water level just covers any pebbles used for elevation. Avoid fully submerging the entire plant for extended periods, as this can lead to rot. Within hours, the plant’s outer stems begin to unfurl, with inner fronds slowly spiraling open. Full revival, from a dry, brown ball to a green, hydrated plant, can take a few hours to a day or two.
Caring for Your Resurrected Plant
Once revived, care involves mimicking its natural wet and dry cycles. While it needs consistent moisture when active, allowing it to dry out periodically prevents rot and encourages dormancy. Keep the plant hydrated for several days (e.g., 5-6 days), then allow it to dry completely for a day or two, or even a week, before rehydrating to prevent continuous submersion. For growth, place it in bright, indirect light, such as an east or west-facing window. Direct sun can scorch its fronds.
The Lazarus plant tolerates temperatures between 65 and 85°F (18-29°C) and flourishes in moderate humidity, often provided by a water-filled pebble tray. Intentional dormancy cycles, allowing it to dry out completely every few weeks or months, ensure its longevity. This cyclical rehydration and desiccation is key to its sustained vitality.
Troubleshooting and Common Issues
The Lazarus plant can encounter common issues. Mold or rot is a frequent problem, caused by overwatering or insufficient air circulation. If left in standing water too long without a dry period, tissues can become mushy and develop a sour odor. To prevent this, ensure regular dry periods and good airflow. If mold appears, remove the plant from water, rinse, trim damaged parts, and allow it to dry completely for several days or weeks before rehydration.
If a plant fails to revive or turn green, remaining brown and curled, it may indicate insufficient humidity. Misting with distilled water or ensuring enough water in the tray can help. A plant might be dead if its roots were severely damaged or if subjected to irregular wet-dry cycles that prevent proper preparation for water stress. Browning or crisping fronds during its active phase often signals too much direct sun or inadequate water. An earthy smell during initial rehydration is normal.
Beyond Revival: Uses and Interesting Facts
The Lazarus plant holds significance beyond its revival, symbolizing hope, rebirth, and resilience. Its transformation from apparent death to vibrant life makes it a popular novelty. Culturally, it has been used in traditions, sometimes as a lucky charm or in rituals.
Selaginella lepidophylla is not the only plant capable of such recovery. Other “resurrection plants” exhibit similar desiccation-tolerant properties, including mosses and ferns like Myrothamnus flabellifolius and Pleopeltis polypodioides. These plants demonstrate nature’s adaptations to harsh environments. The Lazarus plant can endure prolonged dormancy, remaining viable for years, even decades, without water before rehydrating successfully.
