In deciding what plant to experiment with rooting with sage, I made this chart.  I found it very useful although it is not fully complete, since it only has plants that I have attempted to root so far.

Plant(english(latin))	family	rootabily (1=low 10=high)*	usual time to root
apple (Malus pumila)	rose	2	3-4 weeks
apple (Malus pumila) rootstock (various)	rose	4	2-3 weeks
crab cactus (Schlumbergera truncata)	cactus	3	3 weeks
jade plant (Crassula ssp*)	orpine	4	2-3 weeks
plum (Prunus ssp.*)	rose	1	?
rose (Rosa ssp.)	rose	2	3-4 weeks
rosemary (Rosmarinus officinalis)	mint	1	?
sage (Salvia offininalis)	mint	5	2-3 weeks
sorrel (Rumex ssp.*)	knotweed	4	1-2 weeks

ssp* a biology/horticulture term meaning subspecies. 


Rootability Scale: this is all based on my experience, so everyone will find it slightly different depending on the conditions.
