Jotunn

A N S W E R S

When our creativity has no more solutions, we just need to go out in the woods, and trees will give us the answers.

Thomas Allocca

What we do _ Jotunn is a private botanical collection, started in October 2006 in Sant'Elia Fiumerapido, with the name Madake Bamboo Collection- The name changed in June 2024, with new experimental fields in Roscigno and Sant'Angelo a Fasanella within the National Park of Cilento, Vallo di Diano, and Monti Alburni. Jotunn is focused on experimenting and reproducing bamboo plants selected for their high potentials in terms of aesthetics, timber, anti-oxidatice compounds, and resilience to thermal stress.

Why we do it _ Jotunn is aimed at creating superior-quality cultivars, through natural systems, for genetic preservation and improvement of high-quality bamboo species, useful in timber and anti-oxidative compounds production, and interor, garden, and landscape design.

How we do it _ Cultivation and reproduction systems are mainly focused on increasing carbon and silicon content of the underground biomass, which means higher cellular-wall thickness of both underground and aboveground biomass, which means higher resistance to thermal stress, water stress, parasites, electromagnetic waves, air and soil pollutants, acidic rains. No industrial chemicals or laboratory technology are applied. Mother plants come to the collection as natural divisions from original species from nature, and reproduced at the collection through rhizome, culm, and branch division, preserving the original genetic heritage. About the plants that we just have the suspect that they were reproduced from laboratory plants, or using a laboratory technique, we first isolate them, and if later we have certainty of our suspect, we destroy the plants through fire.

The Knowledge Behind _ Jotunn was created and it is owned by Thomas Allocca, internationally recognized as an independent researcher and journalist specializing in timber bamboo. His work has been published and recognized by some of the most prestigious international institutions, including The European Bamboo Society, The American Bamboo Society, The World Bamboo Congress, The National Botanic Gardens of Iceland at Akureyri, and The Royal Botanic Gardens at Kew.

The Name _ Bamboos are usually classified in dwarf, small, medium, big, giant, majestic, according to their height. Dwarf, under 1 m. Small, 1-4 m. Medium, 4-8 m. Big, 8-12 m. Giant, 12-24 m. Majestic, 24-40 m. Jotunn means "giant" in the Norse language, and it refers to the giant species Phyllostachys Bambusoides that started the collection and the experiments.
