Cosmos - pot on or bin it?
I sowed some cosmos too early this year and a while ago I posted about flower buds forming on very small plants. I removed the buds on some, and sowed a few new plants which are doing well so I am sorted for my borders now. I did however leave a few of the original cosmos outside of the mini-greenhouse and these are now pot bound and covered in buds. I was thinking of putting these in larger containers along with various multi-headed sunflowers I've got coming on, just for some container displays near the front door. My question is, now that these cosmos have so heavily gone to flower are they worth keeping? Will they put on more vegetative growth from this state? This cosmos is a dwarf sonata, supposedly to 60cm or so, currently about 30cm in a 4" pot:
