Picea mariana 'Laurentian Falls' is a fast growing, robust, irregular-weeping form of black spruce with meandering, snake-like branching and short, soft, gray-green needles. Plants generally will only need staking when young and will eventually form a fairly strong lead shoot that may or may not grow straight upward.
After 10 years of growth, a mature plant will measure 10 feet (3 m) tall and 15 to 20 feet (5 - 7 m) wide, an annual growth rate in excess of 12 inches (30 cm).
This cultivar was found in nature in the early 2000s by an Iseli Nursery representative in Quebec, Canada. For many years, it was being held in evaluation by Iseli Nursery and has only recently (late 2019) been released to the nursery trade. 'Laurentian Falls' is a fantastic conifer that will create wonder in many large conifer collections.
