This cosmos is growing at our MG test garden -- it is a giant! I've grown yellow cosmos in my yard but I've never seen one as big as this one. According to TAMU agrilife extension, yellow cosmos can grow up to 7 ft.
Have anyone grown them this big? Will have to collect seeds of this one...

I did collect some seeds of it and grabbed seedlings before they were pulled up (cleaning the bed - weeds aplenty).
A few have buds already. We'll see how big these will get.
Just browsing the forums and came across this thread. I have had cosmos growing for several years now and I believe this is cosmos sulphureus that I have. It usually gets 6 feet plus.
This picture was taken this year and the fence is 6 feet tall.
Is that one plant? We have a Gardener at our community garden who over planted packets of seeds of this Cosmo and the regular pink and whites. They grew like a forest as tall as sunflowers.
My picture shows a multitude of cosmos plants where past years seeds have decided to take root. They would probably get larger if I thinned them out, but I like that they support each other, because they have very shallow roots and the wind takes them down.
I don't need to collect seeds because they just keep coming up every year, but I collect them for friends. Even the seeds from this year have taken off and look like grass growing at the base of the taller ones.
Even though my cosmos looks pretty ratty this time of year, I leave it for the pollinators until it caves to the low temps. Here are a few pictures of the pollinators that love cosmos:

I misphrased that. Enough to bring down a nice sized branch from our tree and snap the cosmos in two but no hurricane here. Just the aftermath wind passing through.
