I have lots of lovely chrysanthemum cuttings in my greenhouse taken from shoots of last year's plants and they are doing fine. I also experimented by taking a cutting from the stem of a flower my wife bought from the supermarket and it has rooted really well! The only problem is that, although it has a healthy root system it has produced absolutely no new shoots or growth above the soil. I've kept it in my heated propagator for the last three weeks to try and boost it a bit but still no new growth.
Does anybody have any advice about encouraging new shoots or is my experiment doomed to failure and I will be left with a healthy plant with only two leaves forever...
I would take it out of the propagator and let it settle to grow in a normal temperature and just wait.There is no reason for it not to put out new shoots once it starts a steady life.If it should start to get root bound before it breaks then give a weak nitrogen feed.
It will shoot eventually, so long as you have some leaf nodes

I think the answer is in this statement, they are too warm in my opinion, Chrysant like warm feet and cool heads.
I find once rooted an air temperature of 40°-50° F (4°-10°C) ideal
