Hi Frank,

Like I mentioned I have some LSU Purple that I rooted two years ago which I will experiment on, as well. I will move them from my propagation area to a more permanent location this week, so they can reestablish roots ahead of this experiment.
I'll order BM, BI from Jon to play with when he offers cuttings in Feb. I ordered Col de Dame (DFIC 74) cuttings from UCD. That will become fodder for this experiment as well.
