more mums

I am addicted to the 1.00 clearance rack a Lowe's.  I got chrysanthemums in several colors, and here they will bloom all fall, most of the winter, and again in spring, so I was very happy.  Then when I was planting I broke off two nice size stems.  I brought them in trimmed the leaves off, cut the large one in two and put them in a cup of water in my kitchen window.  Less then a week later they are all growing little roots.  I'm so thrilled, I kind of want to go cut more.  
My friend wants cutting of my roses, it looks easy, but I haven't tried it.
I would love to hear what others have successfully, or even unsuccessfully started with cuttings.  

My little cuttings have many roots, some an inch long already, and its growing new leaves.  So cool!

I too have rooted mums from cut flowers, including some very exotic "spoon-petal" varieties that might have been hard to find otherwise. I would guess that any cut stem that includes a node or a branch has a chance of rooting.  Years ago at college I would raid the dumpsters of the botany and horticulture research greenhouses, and obtained quite a few exotic things that way!  The key is to just not count on it working every time, and being thankful when it does...
