Anyone who spends time in the American Rockies has likely come across Mountain Mahogany (C. ledifolius). In the Great Basin, we have a variety that produces very small leaves, twisting trunks, and abundant deadwood. This shrubby plant is Littleleaf Mountain Mahogany (C. ledifolius var. intricatus) and it's one of my absolute favorites. This thread shows the progress of one I collected: a slender example that grew on an exposed ridgecrest above Great Salt Lake. Clearly, the wind had done a number on this plant.

According to my notes, I collected it in February of 2022 and potted it in sifted perlite topped with shredded sphagnum.

Six months later, August of 2022, it blew off the bench and shattered its pot. To my surprise, the roots looked to be actively growing in August. Regardless, into a box it went with a healthy drainage layer of hard Idaho pumice. Over the next couple of years I applied a few guy wires and did some light pruning to gradually move toward the image I had in mind.

After a really strong season of growth in 2024, I set about changing the planting angle to make a less tippy looking composition.

I plan to rewire in summer as long as the plant seems happy with the new arrangement. And then maybe a bit more branch removal in the fall if it feels right. I'm in no rush here though as these are very slow growing and I'd like to keep the momentum up. More to come -- including more Mahogany projects.
 
The tree's covered in happy little extensions that show no signs of slowing down, so I wired the it yesterday and laid out a first draft of the framework. Plenty of growing left to do this year (and many years to come), but it's good to have the basic design in place.

The branch covered with white cloth will come off this fall if everything goes according to plan. The apex needs to move further to the viewer's right, but that can wait until I have more density in the descending branches.

I had a couple mountain mahoganies when in lived in SoCal and I loved them! I think they are a native tree that is under-utilized in the bonsai world. Talking to the nursery manager where I bought the trees (a nursery that specialized in California natives) the key is to make sure you don't overwater. Otherwise they loved the sun and arid conditions. I'm glad to see someone working with this material!
 
I couldn't agree more about the species being under-utilized and about the importance of avoiding too much water. In some ways I treat these trees like pines -- tons of sun and very open substrate.

Which nursery did you get them from?

Tree of Life Nursery... though I just checked their web site and the founders are retiring and they are winding down operations (to close 12/2025). They are turning the 40 acre property into the new headquarters for the Nature Reserve at Rancho Mission Viejo. The Nature Reserve is a 20,000 acre reserve of land that used to be part of the original Rancho Mission Viejo.

They have two mountain mahogany species listed... as well as 25 species of manzanita :)
 
This feels like a lot of the nicer penjing in the national museum's Chinese collection. Definitely looking forward to how this tree develops!
