More like a Helenium. There are a lot of them all almost exactly the same.
No idea about them as cut flowers, we don't go in for indoor blooms.

Thanks, owdboggy. I have planted some heleniums in the past but they have not flowered well. I thought the ones I had planted had also been yellow. However, this may simply be the first year this one has flowered so well. I moved it to its current location in spring too which makes me think it had not done well in its original spot.

yes it is an Helenium and could be one of many. They have about 5 days vase life in my experience.
It is happy in full sun though mine gets light shade from about 2pm and it flowers really well. It is in quite free draining soil.

Many thanks, Seaburngirl.
