American Elm


Vase shaped canopy, with toothed foliage, which turns yellow in the fall. Branches look like spreading fountains. Large mature size. Extremely adaptable and flexible to almost any situation or growing conditions. Our American Elm seed is collected from the center of Calgary, Alberta. Provides shade. Great for creating canopies over pathways and driveways. Also perfect for all other large areas. Other names include White Elm or Water Elm. Native to eastern North America, naturally occurring from Nova Scotia west to Alberta and Montana, and south to Florida and central Texas. First described and named by Carl Linnaeus in his Species Plantarum, published in 1753. Small purple brown flowers that are wind pollinated, emerge early in spring before the leaves. American Elm is wholly insensitive to daylight length (photoperiod), and will continue to grow well into autumn until hit by frost. Occurs naturally in an assortment of habitats, most notably rich bottomlands, floodplains, stream banks, and swampy ground, although it also often thrives on hillsides, uplands and other well-drained soils. To prevent the spread of Dutch Elm Disease into Alberta, the Government has banned pruning all Elm, between April 1 and September 30. Pruning should only be done when beetles are not active, between October and March. All tools used on diseased elm should be disinfected. All elm materials should be disposed of at City landfills – Stored elm firewood is an ideal breeding ground for elm bark beetles.
