Cryptomeria japonica 'ARAUCAROIDES' Japanese cedar
Cryptomeria
Cryptomeria is a genus of conifers in the cypress family with only a single living representative today, yet its story reaches far beyond the forests of modern Japan. Fossils show that its ancient relatives were already growing in the Early Cretaceous and that during the Tertiary they covered large areas of Eurasia and North America, forming humid, warm forests with high air moisture. The genus was described by the Scottish botanist David Don (1799–1841), who separated it from the then broad group of taxodia and gave it the form in which we know it today. Its only species, Cryptomeria japonica, comes from Japan, where it forms mountain forests on the islands of Honshu, Shikoku and Kyushu. In the wild the species reaches impressive dimensions, up to around sixty metres in height, and its reddish brown bark peels in long strips, earning it comparisons with the sequoias, although it has finer needles and smaller cones.
The Japanese cedar entered European science thanks to the Swedish naturalist Carl Peter Thunberg (1743–1828), who described it at the end of the eighteenth century during his stay in what was then a closed Japan. While Don established the boundaries of the genus, Thunberg captured the species itself as he saw it in the Japanese landscape, forests wrapped in mist through which gentle shades of green flicker as light breaks and scatters across the branches, giving the stands an almost sacred appearance. It is no wonder that cryptomeria, known as sugi 杉 in Japan, gained such a strong place in local culture. The Japanese valued it not only for its wood, which is light, durable and pleasantly scented, but also for its calm, upright silhouette. They planted it around shrines as protection from wind and rain, and the famous avenues, for example at Nikko, still show how deep their relationship with the tree was. In everyday life it served as material for houses, baths and boats, but also as a monumental tree that reminds a person that he stands before something older and more enduring than himself.
Japanese cedar is a species that consists of so many disparate varieties, often so different from the species that you doubt whether the plant is still a Japanese cedar at all. This variety proves the point.
Araucaroides is a picturesque and yet bizarre looking Japanese cedar with long, upright, unbranched twigs that look like woven ropes. They only branch out at the tips leaving the whole lengths smooth as snakes on a diet. The needles are curved, inward-pointing, bright green as they emerge and emerald green in all seasons apart from winter when they turn purplish or bronze. The name was chosen well since this plant does resemble araucaria (monkey puzzle tree) when young. It was found already in 1859.
It grows moderately into a widely conical, irregular shape, and needs quite some time to start looking dense and stately. For years it remains thin and airy. It will grow in almost any well-drained soil, but for best results grow it in fertile, deep, always moist soil. It requires no maintenance, pruning is not necessary but can be trimmed in early spring after all frosts. It is hardy to about -27°C without protection (USDA zone 5b).
