Re: propagating euphorbia

Pam,

I think you're correct in assuming that stem cuttings will root.  I've 
only rooted the smaller E.polychroma, but have had good luck both with 
new growth in the spring, and also with mature stems taken in the winter.  
I treated these as for the other herbaceous perennials and alpines: stems 
were dipped in a talc-based rooting powder and inserted in a porous 
potting mixture [regular peat-perlite and covered for the spring 
cuttings; pure coarse sand in an open cutting bed for the late fall 
cuttings.]

Also, I find a recommendation [Jelitto and Schacht, HARDY HERBACEOUS 
PERENNIALS] to soak fresh cuttings in lukewarm water for 15 minutes to 
prevent the latex from sealing of the surface where roots must form. And, 
of course, to be cautious, keeping latex out of your eyes or open wounds.
