Can you suggest some low-maintenance plantings for Park City, Utah?
What perennials, shrubs, or small trees grow well in landscapes in Park City, Utah? I realize that is a broad question, but the landscape I'm renovating for a friend will only be occupied part-time so it needs to be as self-sufficient as possible. I'm looking for some recommendations of "old faithfuls" to get us started I'm familiar with gardening in the Northeast and the Southeast.
Summit County Utah
We have a publication that might be of some interest on landscaping in Utah's high mountain valleys (https://extension.usu.edu/files/publications/publication/HG_500_2.pdf . Be aware that some plants listed might not thrive at higher elevations. If I were going to do a low maintenance landscape as you describe, I would consider the following:
Betula occidentalis (if in a moist area)
Prunus virginiana 'Canada Red'
Juniperus (many choices)
Mahonia (Berberis) repens
Rhus glabra 'Cismontana'
Rhus aromatica 'Grow-Low'
Achillea millefolium (may be invasive)
Dianthus 'Zing Rose'
Lupinus (especially native ones)
Narcissus (not tulips, deer love them)
Hopefully these will give you a starting point. Another great source is the PlantSelect program (plantselect.org) which has a great list of plants tested at high elevations in the Rocky Mountains.
Good luck and thanks for the question!
