Thank you in advance :-)

    I vote rudbeckia😊
    In London. Keen but lazy.
  • I'd say Helenium.
    As far as I know Rudbeckia dont' grow that tall.  Not to say that someone hasn't bred a giant one tho ;)
    @ Silversurfer would be your best bet for a definite ID 
  • There are tall rudbeckia,  R. maxima, gets 6ft.

    I think you have a helianthus though, there are several perrenial sunflowers that get that big and look like that. 
  • Looks like a rudbeckia to me.

    I think the leaves look more like Rudbeckia.

    I’d say Helianthus.
    How can you lie there and think of England
    When you don't even know who's in the team

    I'd say Helianthus too. 
    Rudbeckias tend to have more of a 'cone'. Leaves look different too. 
    It's a place where beautiful isn't enough of a word....



    I live in west central Scotland - not where that photo is...
  • Ahh  :D still the argument continues then! 
    I meant helianthus not helenium... and my money is on that, but my mum swears it’s rudbeckia  :#
