Jotunn

The best architecture walks at the forests' pace. Neither slower, nor faster.

What  _  Jotunn is a botanical project, launched in June 2024, focused on experimenting new growing and reproduction systems applied to high-value timber bamboos.

Why  _  Jotunn is aimed at creating superior cultivars, improving aesthetics, quality of timber and anti-oxidative compounds, and resilience to thermal stress, for applications in architecture, landscape, and land fertility.

How  _  Cultivation and reproduction systems are mainly focused on increasing the organic carbon and silicon content in the biomass, without industrial chemicals or laboratory technology. Mother plants are sourced from wild groves or private collections, strictly avoiding tissue-culture plants. Reproductions are made through rhizome, culm, and branch division, preserving the genetic heritage of the mother plant.

Who  _  Jotunn is owned and funded by White Oak Arkitecture, directed by Thomas Allocca, with the support of several private landowners in Italy, for experimenting the growing systems at different latitudes and altitudes. Thomas Allocca has been an independent researcher, collector, and journalist, specializing in timber bamboo since 2006, internationally recognized with publications by the prestigious international institutions The European Bamboo Society, The American Bamboo Society, The World Bamboo Congress, The National Botanic Gardens at Akureyri (Iceland), and The Royal Botanic Gardens at Kew (England).

Name  _  In the Norse language, Jotunn means "giant", referring both to "big physical size" and "being of great value".

Carbon and Silicon for Superior Timber and Land Fertility

1    Bambusa Chungii

pachymorph    sympodial    H 12 m    D 6 cm    -4 °C    BC-2026 Vietnam

2    Bambusa Oldhamii

pachymorph    sympodial    H 16 m    D 12 cm    -8 °C    BO-2010 Taiwan    BO-2012 China    BO-2025 China

Described the first time in 1868 by Mr. Oldham as a new Bambusa naturally growing on Taiwan.

3    Bambusa Taiwanensis Diana

pachymorph    sympodial    H - m    D - cm    -12 °C    BTD-2014 Italy

Selected in 2014 by Thomas Allocca from BO-2012 China. Published by the American Bamboo Society.

4    Bambusa Textilis

pachymorph    sympodial    H 12 m    D 6 cm    -12 °C    BT-2026 China

5    Bambusa Vulgaris Vittata

pachymorph    sympodial    H 16 m    D 12 cm    -4 °C    BVV-2025 Thailand

6    Phyllostachys Bambusoides

leptomorph    monopodial    H 24 m    D 16 cm    -20 °C    PB-2006 Korea    PB-2025 China

The mother land is Korea, probably south Korea. Exported to Japan around year 1620. The origin of the cultivar from China is unknown, but it is a possible theory that it arrived from Korea, not from Japan. From China it was then spread to Tibet, and from Tiber to India through the Apatani tribe. The western cultivars arrived to Europe and the United States of America from China and Japan in the first half of the 20th century, and from the USA to Canada.

7    Phyllostachys Bambusoides Tanakae

leptomorph    monopodial    H 12 m    D 8 cm    -24 °C    PBT-2020 Japan

The most beautiful subspecies of Phyllostachys Bambusoides, with higher cold resresistance.

8    Sasa Kurilensis

leptomorph    monopodial    H 2 m    D 2 cm    -28 °C    SK-2026 Japan

The name Kurilensis means from Kurili, a group of islands in south-east Russia between the Okhotsk Sea and the Pacific Ocean, but the motherland of this bamboo is the Hokkaido island, in northern Japan.

9    Semiarundinaria Fastuosa

leptomorph    monopodial    H 8 m    D 4 cm    -20 °C    SF-2024 Japan
