Mandan Ash...High Altitude?

Asked October 7, 2015, 12:30 PM EDT

A good friend of mine passed away and I'd like to plant a tree in his honor. The location would be in the Wet Mountain Valley where the elevation is 7,867 ft. His family would like a Mandan ash on the north side of the church. How well will this type of tree do at this location?

That's a great idea Tim.

There are many types and varieties of Ash trees, but I've never heard of Mandan ash. I could not find any reference to Mandan ash online or in tree lists.
The closest one is Mancana Manchurian Ash (Fraxinus mandshurica 'Mancana'). This may be hard to find at a nursery. You may instead want to plant
Patmore ash
Dakota Centennial ash
Prairie Spire ash or
Marshall Seedless ash

At 7900 ft, it would be better to plant in spring than in fall months.

Ash trees in the Front Range may eventually be damaged or killed by Emerald Ash Borer, but so far this insect has been confined to Boulder. It is less likely to become a problem at higher altitude in S. Colorado.
