Scientists have discovered a fern that forms rare-earth crystals. The plant, Blechnum orientale, produces monazite inside its tissues. This is the first natural observation of monazite formation in plants. The discovery could revolutionise sustainable extraction of critical elements.

Unusual Crystal Formation

The crystals contain neodymium, lanthanum and cerium. They self-organise in a “chemical garden” pattern inside the plant. Researchers used microscopic imaging and chemical analysis to confirm this. The fern absorbs rare-earth elements from the soil naturally. It acts as a hyper-accumulator, concentrating REEs efficiently.

Sustainable Mining Potential

Rare-earth elements are essential for electronics, EVs, and renewable energy. Current mining methods are environmentally damaging and resource intensive. Phytomining with ferns offers a cleaner, more sustainable alternative. Scientists hope to extract the crystals for practical use safely. This could reduce ecological impact of rare-earth element production.

Scientific Implications

The finding changes our understanding of biomineralisation in plants. It shows that plants can create complex minerals naturally. Researchers are exploring if other plants share this capability. This may reveal new ecological and evolutionary insights. The discovery opens doors for biotechnological applications in materials science.

Next Steps for Research

Teams plan to test other ferns like Dicranopteris linearis. They aim to optimise extraction and scaling methods for REEs. Understanding the growth mechanism could lead to industrial applications. This breakthrough could link plant biology and clean technology. The fern may be a model for sustainable mineral production.
