Tithonia: Is this a record?
My Tithonia plants have reached 2.46 metres in height - around 8ft. Things do grow big here, but they are intent on full-scale border domination. For an idea of scale, that’s Helenium Moerheim Beauty peeking out underneath, with Agastache Black Adder getting a bit above itself too:


Mountainous Northern Catalunya, Spain. Hot summers, cold winters.

What’s an obedident (obedient?) plant @ForTheBees? Does it sit up and beg?
In the sticks near Peterborough
I picked up one from a bunch that we're about three times the height of the rest and they're normally quoted as reaching 90cm so I'm expecting it to be disappointingky not tall next year!
