BL I think it's worth trying - this post on an old thread suggests that the stems can form roots
Cosmos are lovely flowers- I've been growing the Purity ones for the first time this year.
Interesting what you said about the white roots. One of mine got really battered earlier this year and the stem was badly bent- the plant was still alive so I just left it resting on the ground.Just by chance I picked up the stem the other day and there are loads of roots coming out of the stem that was on the ground. So I guess it is possibly to take stem cuttings
Mine will probably get leggy too as they're on the dining room windowsill at the moment and will be going into the east-facing mini greenhouse later, so let us know how yours get on if you plant them deep.
