These are two of the four stems I have in the three leaf/30/60/90 degree rotated configuration. They also seem to rotate in threes. I will be propagating the heck out of these in the future.
I also have them growing with the standard two opposing leaves/90 degree rotated alternating configuration, as well as some that are actually growing single/alternated 180 degree rotation. The single leaf ones will probably go away soon, because I'm not a fan of the less leafy configuration.
I'll be planting them surrounded by Oregon Stonecrop since I got my garden cleaned up last year. Another interesting story about the Oregon Stonecrop: I've only found it growing in one place in all of Southwest Washington - a small rocky hillside on top of a 3000 foot hill.
