Flower i need identifying

[greyshark]

I would be grateful if someone could identify this flower for me. The tallest plants are from 1.2 to 1.8*metres high. I am from the UK and this plant is growing in my garden. I know that they grow from tubers. Thanks, Paul

Hi Greyshark,

You don't say where this plant is, if it's growing in the wild of your area, and the picture color seems off, but since you describe it in meters I'm thinking you might be in Canada.* It might be some type of sunflower considering the height.

Apologies. I have updated my original post.

Dahlia?

I have just been informed that it is may be a rubeccia.

Greyshark, I thought of Rudbeckia too, but I've found that they either have a dark brown eye or a green one.* They are usually called black eyed susan. You also said that they grow from a tuber so I ruled that out.* I did a google with it spelled Rudbeckia and clicked on 'Images'.

Here's Rudbeckia 'Cordoba'.* Maybe the 'eye' ages to this color on yours.

If there is no tuber I also thought of Heliopsis which is a sunflower.

Greyshark, I also have this flower in my garden. It just appeared last week. I didn't plant it so I assumed it was a sunflower that a critter planted for me. It sure looks like a rudbeckia though. Happy gardening, Coralbelle...
