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...

Impressive!

When I lived down south I sometimes saw them very large but not this large!

The little emberizids love the seeds!
Keep going!

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.
