It's probably against the law for you to do this.
There are good reasons it is.
The chestnut blight fungus, Cryphonectria parasitica (formerly Endothia parasitica), virtually eliminated the once-widespread American chestnut tree.
The chestnut blight was accidentally introduced to North America around 1900-1908, either through imported chestnut lumber or through imported chestnut trees. In 1905, American mycologist William Murrill studied the disease, isolated and described the fungus responsible (which he named Diaporthe parasitica), and proved by inoculation into healthy plants that the fungus caused the disease.
Dutch elm disease (DED) is a fungal disease of elm trees which is spread by the elm bark beetle. Although believed to be originally native to Asia, the disease has been accidentally introduced into America and Europe, where it has devastated native populations of elms which had not had the opportunity to evolve resistance to the disease. The name Dutch elm disease refers to its identification in the Netherlands in 1921; the disease is not specific to the Dutch Elm hybrid
Certified arborist removing infected elm in Saint Paul, Minnesota.The disease was first reported in the United States in 1928, with the beetles believed to have arrived in a shipment of logs from the Netherlands destined for use as veneer in the Ohio furniture industry. The disease spread slowly from New England westward and southward, almost completely destroying the famous Elms in the 'Elm City' of New Haven, reaching the Detroit area in 1950 , the Chicago area by 1960, and Minneapolis by 1970.
I'm not saying the Canada Red Cherry tree branch you plan to have sent to you is infected with anything but you don't know if it is or isn't.
If it is a choke cherry there are native species in the USA. It may not have the same sentiment but should look the same.
At least check with the Agriculture department on the legality of having this shipped to you.
