Great article, I picked up a few of these last spring and they are still going strong with nice green color and a few light purple flowers still left. They have even outlasted the fall chrysanthemum planted in the same bed. In our area they were sold as premium annuals at a price of just under $5 ea. I would like to take some cuttings to root and try to save for next spring. You gave great directions on cuttings and I have done that before but have never tried to take fall cuttings and keep them overwinter. Would you have any other suggestions for me?
Overwintering cuttings would require enough light to sustain them for the winter. If you have a nice sunny window, I'd sure try it. You can always cut them back and go again if they get too leggy. They root easily.
I cut 3 plants up into about 15. I had to wait a bit longer for the show, but my 'el cheapo' ways wouldn't let me buy 15 of these plants when I could make more.
