I received this dwarf mugo as a gift in 2017 (I think), I'm pretty sure it's a "Valley Cushion." I also got this pot, so I potted it up and let it grow, trimming and wiring in late summer. I didn't like the boring s-curve it came with so I wired it. But it really needs a grow pot and some development, so it went into a terra cotta pot this spring:
Now it has a new front and an interesting bend. Downwards growing branches will be trimmed later this year. Trimming long shoots has produced back buds with tiny 1/8" needles:
After I potted it in the bonsai pot and heavily fertilized, 5 buds appeared low on the trunk. I've kept 3 of them to thicken the base. My plan is to let most of the tree grow out for at least a few years, except the primary branch which will be kept tight. The tree will be a shohin, it's now 6" high and 10" wide. It needs lots of development, but it's a fun project.
