Azara microphylla 'Variegata'
I went it my local nursery looking for material to practice air-layers on, and found this one. I've really enjoyed working with this species! It has some quirks and I have not seen anyone attempt to use it for bonsai, but overall, it's really fun, fast growing, and has a nice growth habit. It's also readily available at nurseries here, and I've seen a number of examples in landscaping, so I think I'll keep trying this plant. I like it a lot better than
Buxus as far as small-leafed evergreens go.

these images show something of the "two trees" i saw in it. really, only the top part (to be air-layered off) is good material, but I'll keep the bottom to see what happens.

cut the layer--but I think there's much too much green (again, colorblind), and it's a little close together

attempt #1 and #2

in July, I checked for roots...and found none! It had completely bridged; I blame a bad initial cut, as well a poorly secured pot (that second mistake I made again...). there was some start to the layer working, as you can see the callus and the difference in caliper above the layer

cut it again and placed another pot on. I posted a
thread about this here.

This tree has been very responsive to pruning. Here is a piece I pruned back substantially (probably about 8 full nodes!) in the apex about two weeks later. Notice that It has put out 4 new shoots!

The biggest downside to this tree that I've observed--and this may be specific to the variegated cultivar--is that fresh buds tend to burn very easily. They turn black and just...drop. I asked a question about that
in this thread. I'm still figuring out how to avoid this, but I think fresh buds need to be out of the sun on hot, sunny days. The new shoots also tend to grow in bright pink!! It's very pretty.

as it is today. note that i've now properly wired in the air-layer pot

I have some good evidence that the air-layer is starting to work this time. I have a LOT of growth near the bottom tree's apex (just under the layer) and the main pot is drinking a lot less water. Next month, I'll cut a window in the pot as suggested and demonstrated by
@BobbyLane and evaluate whether it can be separated in the fall, but I'd rather avoid that. If I do separate at that time, I will provide bottom heat over the winter.
The Future
I'll likely wait until spring to separate the layer. As you can see, the branch structure of the upper portion is a very neat and even left-right-left thing. I'll probably remove that first heavy branch on the right and the lay the branches flat. The bottom is not really what I'm looking for, but I'll keep it around; it's bursting with roots, so I think giving that a decent first prune would be a good start.
