Plans to Propagate Sweet Potato Vine

After all my winter reading, I was very jazzed about adding Sweet Potato Vine to my container garden.  I've seen beautiful pots with long trailing vines and I wanted these in my own landscape.  I have purchased a few vines and have had much success with propagating them through stem cuttings.  Here's what works for me:
Here is a photo of a plant I bought in the smallest size at m local Farmer's Market ($1.49).  I have cut, rooted and planted this maybe 4x already.

Sweet Potato Vine

You want to have a couple of inches of stem to root.  Choose a stem piece that has some grown shoots, cut all the younger shoots (I cut at an angle), so that there is only 1 major leaf on top.  I would cut just below where the mysterious finger is pointing, then cut the young shoots off - all except the top.

Place in a see through jar of water in a sunny spot, making sure to top off the water every few days due to evaporation (especially if they are outside like mine are)

I've read the rooting should take 2 weeks.  As it gets warmer outside (96 degrees today) I find they are rooting A LOT faster!   Below is a very healthy piece with some great looking roots!  I'm pretty proud of this one.

I planted this one in a small pot along with another I pulled from the jar 2 days ago. as  In a few weeks, I may be taking cuttings from this guy!  Or, maybe I'll make up a nice pot for a friend!
