The family Sciadopityaceae, and a living fossil that has no close relatives. This distinctive evergreen tree can grow up to 27 meters tall, with brown shoots bearing whorls of flexible green cladodes, which look like leaves but are actually composed of stem tissue. The cones, which mature in about 18 months, are 6-11 cm long and have flattish scales that open to release seeds. Koyamaki is a slow-growing tree that makes a distinctive dark green impression in the landscape. It prefers rich, moist soil and full sun. Despite its high cost and slow growth rate, it remains a popular tree for landscaping and is often cultivated as an ornamental or for its timber. Koyamaki, also known as Japanese umbrella pine, was chosen as the Japanese Imperial crest for Prince Hisahito of Akishino and was introduced to Europe by John Gould Veitch in the 19th century. Infrared microspectroscopy has identified Koyamaki as the principal source of Baltic amber. Its unique whorled form and rich history make Koyamaki a stunning and meaningful addition to any garden.
