Sounds prolific - I don't grow them, but its not unusual to have sunflowers with several blooms on a stem.

Some varieties can be that prolific, though not usually the ones grown for their edible seeds. Most of the branching kinds are good for bird seed, though. Do you know the variety name?

hi, thank's for your replies, i was thinking i had some sort of "super sunflower" ha ha,
the seeds where a free gift from Bramhall construction & they are " Lemon Queen" variety.
Thanks Dave.

Yep, 'Lemon Queen is one of the more prolific ones. I have seen incredible "hedges" of these while on vacation in southwestern Colorado. Put on your sunglasses and enjoy, Dave! : )
