Pteridium aquilinum (bracken, brake or common bracken), also known as eagle fern, is a species of fern occurring in temperate and subtropical regions in both hemispheres. The extreme lightness of its spores has led to its global distribution.
 
The preservation process uses natural, non toxic products. Preserved plants are 100% biodegradable. The natural sap of the plant is replaced with a preservative similar to sugar, to maintain the plants flexibility and organic dyes are used.
