From Patagonia with Love

Three years ago, we wrote about a new, winter hardy selection of bushy muhly grass, Muhlenbergia dumosa, collected by Patrick McMillan in the Patagonia mountains of Arizona, that should be much more winter hardy than the Zone 9 genetics that have been in the trade since the 1980s. From our initial planting in 2020, our specimen has now endured four winters, including a low temperature of 11 degrees F, and is still looking great, as you can see below. Mature size is 5′ tall, with stems that arch out to 7′ in width. We’ve begun the propagation process to make this available, and are aiming for January 2026.
