The Japanese larch, from the mountains of Honshu Island, is hardy in Finland to zone III, i.e. quite far inland. The species has grown at Mustila since about 1910 and has suffered little or no damage even in the coldest winters of last century. However, when young the seedlings are rather tender to autumn frosts due to their maritime origin. Autumn frost can also damage the flower buds.
The bluish tone of the needles clearly distinguishes this species from the other larches growing at Mustila. The cones, distinctly rose-shaped, are highly attractive.
Japanese larch is found at Mustila near Juhlapaikka (Festival Area), with one very impressive broad-crowned individual at the edge of the wood.
