I have thes plants that look like giant dandelions, the largest is over nine feet tall- any ideas as to what they are?

Question

These plants are huge in height while onle being a foot orso in diameter. They look "leggy" and get sun for 12+ hours a day. They have multiple stems from one root. Stem diameter is 3/4". The yellow fowers turn into puffballs that are flatter than the ones on the lawn. I'd  like to find out what theae are.

I'm entering one in the County Fair(Merced, CA) in June. I don't see how I can lose! Since I've been feeding them for the last couple of weeks they put on foot oso. Anybody know of steroids for dandelions?

Thank you,

Bob Merlin
