The resurrection plant, a marvel of nature, appears to come back to life from a dried state after receiving water. It’s a common name for a group of remarkable species that can survive almost complete dehydration, a process known as anhydrobiosis. For anyone fascinated by botany or looking for a resilient houseplant, understanding these plants opens a window into extreme survival.
They curl into a tight ball when dry and unfurl vibrant green fronds when watered. This isn’t just a neat trick; it’s a profound biological adaptation. This article explains everything about these incredible organisms, from how they work to how you can care for one.
Resurrection Plant
When people refer to the resurrection plant, they are usually talking about one of two primary species: Selaginella lepidophylla (also called the Rose of Jericho) or Pleopeltis polypodioides (the resurrection fern). Both share the amazing ability to lose up to 95% of their water content and enter a state of suspended animation. They can remain in this dry, dormant state for years, only to revive within hours of contact with water.
This capability is exceptionally rare in the plant kingdom. Most plants would die quickly under such extreme water loss. The resurrection plant’s secret lies in its cellular structure and protective sugars that preserve its essential machinery until water returns.
Scientific Classification And Common Species
It’s important to note that “resurrection plant” is a descriptive term, not a scientific one. Several unrelated plants have evolved this trait independently. Here are the most well-known types:
- Selaginella lepidophylla: This is a spikemoss, not a true moss, native to the Chihuahuan Desert. It’s the classic “ball” plant sold as a novelty. It is a vascular plant, meaning it has primitive tissues for transporting water.
- Pleopeltis polypodioides: This is a true fern that grows on the branches of trees in the southeastern United States. It turns brown and curls when dry, blending in with tree bark, and greens up after rain.
- Myrothamnus flabellifolius: A woody shrub from southern Africa, this is one of the few resurrection plants with a woody structure.
- Craterostigma plantagineum: A small flowering plant from Africa that is a model organism for scientific research due to its rapid recovery.
The Biology Of Coming Back To Life
The process these plants undergo is called desiccation tolerance. It’s a complex survival strategy involving several key steps:
- Water Loss Sensing: As the environment dries, the plant senses the initial loss of moisture.
- Protective Sugar Production: The plant produces large amounts of sugars, like trehalose or sucrose. These sugars form a glass-like matrix inside cells, stabilizing membranes and proteins and preventing them from tearing apart or denaturing.
- Controlled Dehydration: The plant doesn’t just dry out; it manages the process. Leaves curl inwards to minimize surface area and slow further water loss. Chlorophyll is broken down to prevent photo-oxidative damage from the sun.
- Metabolic Shutdown: At extreme dryness, all metabolic activity effectively stops. The plant is not dead, but in a state of cryptobiosis.
- Rehydration and Repair: When water returns, the plant absorbs it rapidly. The protective sugars dissolve, cellular structures rehydrate in the correct order, and repair mechanisms fix any minor damage incurred during drying. Photosynthesis resumes often within hours.
Natural Habitat And Evolutionary Advantages
Resurrection plants typically inhabit extreme environments where water is unpredictable. These include rock outcrops, desert margins, and epiphytic perches on trees. Their adaptation is a direct response to harsh conditions where other plants cannot compete.
The evolutionary advantage is clear: they can wait out prolonged droughts. While other plants die, the resurrection plant simply pauses. When the rare rain comes, it can reactivate quickly, grow, and reproduce before the environment dries out again. This allows it to occupy ecological niches with little competition.
Key Habitats Around the World
- North American Deserts: Selaginella lepidophylla thrives in the arid regions of Texas, Mexico, and the southwestern U.S.
- Southeastern U.S. Forests: The resurrection fern is common on live oak and cypress trees from Florida to North Carolina.
- Southern African Scrublands: Rocky areas host species like Myrothamnus.
- East African Highlands: The genus Craterostigma is found in seasonally dry areas.
How To Care For A Resurrection Plant
Caring for a resurrection plant is very simple, making it an excellent choice for beginners or those who forget to water. Most people acquire the dried Selaginella lepidophylla form. Here’s a straightforward guide.
Initial Resurrection And Watering
- Place Your Plant: Set the dry ball in a shallow bowl or saucer.
- Add Water: Use distilled, rain, or filtered water if possible, as tap water minerals can build up. Pour about half an inch of water into the bowl.
- Observe the Change: Within an hour, you will see the stems begin to unfurl. Full expansion and greening can take up to 24 hours.
- Drain and Dry: After it has been green for a few days (usually 3-4), remove the water and let the plant dry out completely. This drying cycle is essential for its long-term health.
You should repeat this cycle every few weeks. Constant submersion will cause rot and eventually kill the plant. It needs a period of desiccation to thrive.
Light, Temperature, And Long-Term Maintenance
Resurrection plants prefer bright, indirect light. Avoid direct, hot sunlight, especially when wet, as it can scorch the leaves. They do well at average room temperatures. They have no need for soil or fertilizer when kept in their dormant-active cycle. Simply enjoy the natural process of resurrection and drying.
If you wish to try planting it in soil (which is not necessary), use a very well-draining cactus mix and pot with drainage holes. Water only when the soil is completely dry. This mimics its natural cycle more closely, but success can be variable.
Common Misconceptions and Mistakes
Many people misunderstand the needs of these plants, leading to their premature demise. Here are the top mistakes to avoid.
Keeping The Plant Constantly Wet
This is the number one error. The resurrection plant is a drought specialist. Its biology requires a period of dryness. If left in water permanently, it will develop mold, turn black, and rot. It’s health depends on the cycle.
Using Tap Water Exclusively
Hard tap water leaves mineral deposits on the delicate fronds. Over time, this can interfere with water absorption and photosynthesis. Using purified or rainwater is best for long-term vitality.
Expecting Eternal Life
While incredibly resilient, an individual resurrection plant’s lifespan is measured in years, not decades. Each resurrection cycle causes slight cellular stress. With proper care, you can enjoy its transformations for a long time, but it is not immortal.
Scientific Research and Potential Applications
The unique abilities of resurrection plants are not just a curiosity; they are the subject of intense scientific study. Researchers hope to apply lessons from these plants to other fields.
Agricultural Crop Improvement
The primary goal is to understand if genes responsible for desiccation tolerance can be introduced into staple crops like corn or wheat. This could provide a buffer against drought, improving food security in arid regions. While complex, early genetic research is promising.
Medical And Pharmaceutical Storage
The sugars that protect plant cells are similar to those used to preserve vaccines and enzymes in a dry state (lyophilization). Studying how resurrection plants stabilize biological material could lead to better techniques for storing pharmaceuticals without refrigeration.
Space Exploration And Astrobiology
Resurrection plants are considered model organisms for studying life in extreme environments. Their ability to survive near-total dehydration makes them a candidate for studies on long-term space travel and the potential for life in dry extraterrestrial environments, like Mars.
Frequently Asked Questions (FAQ)
How Long Can A Resurrection Plant Stay Dead?
It’s not actually dead; it’s dormant. In a dry state, a resurrection plant can survive for many years. There are herbarium records of specimens reviving after storage for decades, though the success rate decreases with time.
Are Resurrection Plants And Rose Of Jericho The Same Thing?
Often, yes. The “True” Rose of Jericho is Selaginella lepidophylla. However, another plant, Anastatica hierochuntica (also called the Rose of Jericho), exhibits similar curling but is not a true resurrection plant. It is a annual plant whose dead branches curl when dry, but the seeds inside are what survive to grow new plants. The living plant itself does not revive.
Can You Grow A Resurrection Plant From Seeds?
Yes, but it is a slow and challenging process, especially for the common Selaginella. They produce spores, not true seeds. Propagation is typically done by division of a living plant, not from the dried balls sold commercially. For most people, purchasing a dormant plant is the easiest method.
Is The Resurrection Plant Poisonous To Pets?
Resurrection plants (Selaginella species) are generally considered non-toxic to cats and dogs. However, it’s always best to discourage pets from chewing on any houseplants, as they can cause mild stomach upset or become a choking hazard.
Why Is My Resurrection Plant Turning Black?
Blackening is a sign of rot, almost always caused by being kept too wet for too long. You need to immediately remove it from water, allow it to dry out completely, and gently remove any slimy or blackened parts. If the central core is firm, it may recover on its next dry cycle. Prevention is key—stick to the soak-and-dry method.
Conclusion
The resurrection plant is a testament to nature’s ingenuity. Its ability to cheat death by drying is a captivating spectacle that also holds significant scientific value. By understanding its needs—primarily the crucial cycle of watering and complete drying—you can easily care for one of these ancient survivors.
Whether you keep it as a low-maintenance conversation piece or are intrigued by its biological secrets, the resurrection plant offers a unique connection to the extreme resilience of life on Earth. Remember to source plants responsibly from reputable sellers to ensure wild populations are not harmed, and enjoy the remarkable process of life, pause, and rebirth happening right on your windowsill.
