Can anyone name these tall (8-9') bright yellow flowers

Question

tons and tons of blooms, really thick stalk, the leaves look like marijuana leaves - not much of a scent - but just beautiful to look at, and they apparently spread very easily. This is only my 2nd year to have them - I can email u a photo if that might help. Thank you very much.

Answer 1

Maximillian Sunflower?
