Pineapple Sage (Salvia elegans)
Quite frankly I was amazed at the roots that I found when I transplanted four more cuttings into pots. The cuttings had only been rooting for about two weeks in sand and had developed a great start. I took stem tip cuttings with two nodes from a plant I have next to the vegetable garden treated them with rooting hormone and kept them in moist sand for two weeks. I didn't put any covering over them but I may not have had to water as often if I had. (score: 4 of 4)
Catnip (Nepeta cataria)
This one should come as a no-brainer since catmint (a close relative) is so easy to propagate. I did the same rooting procedure as I did for the pineapple sage and had some nice roots on both cuttings I made. (score 2 of 2)
'Violet Dusk' penstemon (Penstemon smallii) is a piece of cake for propagating. This small perennial will grow roots from the end of the cut so internodal cuttings will work fine. Otherwise I did the same as above! (score: 4 of 6)
Hydrangea! (Hydrangea macrophylla)
OK, hydrangeas aren't a new revelation but I thought I'd mention that six new plants came from two branches of the parent plant. Stem tip cuttings aren't necessary and the roots will emerge internodally which means you don't have to have multiple nodes to get some rooting action! (score 6 of 6) One quick propagation tip: if you have large leaves consider cutting the leaf in half to reduce moisture loss. (see picture)
If you're looking for something easy to propagate give one of these four plants a try!
