Blue cedars are relatively fast-growing, long-living trees. With a pyramid shape when they are young, they can grow up to 40 metres high. Their interesting foliage consists of light green or bluish leaves, depending on the type of cedar. They produce feminine and masculine flowers that are not interesting from an ornamental point of view. The cones can take up to two years to mature; then they release their seeds, which we can collect if we wish to plant them.
