Abies mariesii, commonly known as Maries’ fir, is a medium-sized evergreen conifer native to the subalpine and montane zones of central and northern Honshū, Japan. It typically grows at altitudes of 2,460-6,233 feet (750-1,900 meters) in cool, moist environments, often forming pure stands or mixed forests with other conifers and broadleaf species. Maries’ fir reaches a height of 49-98 feet (15-30 meters) and is characterized by a conical crown with a straight trunk. The leaves are flattened, needle-like, and arranged in a spiral pattern on the branches, contributing to the dense foliage. The tree produces dark purple-blue cones that are notably upright and cylindrical.

Maries’ fir is appreciated for its ornamental qualities, including its symmetrical form and attractive foliage. It is used in gardens and parks, particularly in temperate regions, and is valued for its adaptability to a range of soil types, provided they are well-drained. It prefers cool, humid conditions and can tolerate partial shade, although it thrives in full sun. While not commonly used for timber due to its limited size, it is sometimes planted for reforestation and conservation purposes. Gardeners should be aware that, like many firs, it can be susceptible to pests such as aphids and diseases like root rot if not properly cared for.CC BY-SA 4.0
