Abies concolor is a tree.
Abies concolor was already described and the name validly published by George Gordon. It was Friedrich Hermann Gustav Hildebrand, however, who reclassified it into todays valid botanical systematics in 1861 based on a prior description by John Lindley.
The trees are comparatively slow-growing and long-lived. They have a broadly columnar canopy and reach heights of 25 to 40 metres. The plants reach a width of 7 to 10 metres.
Wood and Bark
The bark is smooth and grey.
Abies concolor is evergreen. The dark-green, simple leaves are alternate. They are deltoid with entire margins.
Flowers and Fruits
Abies concolor produces salmon-red flowers in May. The plants are dioecious, pollination takes places by allogamy through the wind.
The trees produce brown cones in summer.
The plants form deep-reaching roots.
Abies concolor is native to the Southwest of the US, Oregon, California, the Rocky Mountains and Mexico.
The trees prefer a half-shady situation on dry to moderately moist soil. The substrate should be sandy, gritty-sandy, loamy, sandy-loamy or gritty-loamy soil with a pH between 8 and 10. They tolerate temperatures down to -29Â°C (USDA zone 5).
