I was turned on to the Empress by an answer that Jan Steinman gave to a question here on the forums. You can check it out here if your interested: How to grow a tree on steroids?
I was showing my sister a picture of the tree and she fell in love with it. She wants one; however, there is a problem, the tree is meant to grow in zones 5-8 and her house is zone 3/4 depending on the year. She lives @ around 6,500 ft in the Livingston mountain range here in Montana.
I was hoping to get some insight. In general, I realize its a stretch (to say the least) to think that I might get one growing up there but I have seen, Elm, beach, willow, cherry .. ext growing in similar conditions so there might be hope. Let me know what you guys think and what steps you think I would need to take in order to make it happen if, in theory, you think it might be possible.
Environment variables (soil):
- Depth class: Very deep (more than 60 inches)
- Drainage class: Well drained
- Permeability: Moderately slow
- Landform: House sits on top of an alluvial fan
- Parent material: Alluvium, colluvium, or alpine till (high volume of moderately large rocks 6x6 in on average I would say)
- Slope range: around 20%
- Elevation range: 6,400 to 6,500 feet
- Annual precipitation: 20 to 30 inches
- Temperature: 60-70 F (summer) -10-30 F (winter)
Please keep in mind that the house is newely built and the land has not been managed (rather wild). I will have the ability to move large volumes of dirt (tractor) and there are plans for installing a pond. In general, it is rather windy and the natural tree is the conifer.
