Look at Helianthus Lemon Queen? apart from the height it looks very like mine?

Looks like it to me. Have a look at my photos. Phil J

its a helianthus but the flowers look too open and dark for Lemon queen. and its not 'compact' enough either. Mylemon queen is 4-5ft tall in my garden.

Yes its much shorter than mine too SBG. I have a photo of mine you can have a look at too Balcony

yes its in my photo gallery too from this time last year.

Thanks everyone for your comments. Gerry has a plant of this growing in his garden He showed me it this morning & told me that the plants growing down on the allotment were from his garden! When I asked him if he knew its name he could only tell me it was from the Sunflower family!

I've just done a search for Helianthus Lemon Queen. From the photos I've seen & from the descriptions I've read it most certainly isn't Helianthus Lemon Queen. It would seem to be from the sunflower family as Gerry said but I can't find a photo that looks like this plant.

yes it is ,i have them .they are late summer spreding perenial will pop up every were ,just pull em up were u dont want them

Thanks, Cristina, for you reply but I think I'm inclined to think it's a member of the sunflower family. It seems that Rudbeckias have a dark cone which gives them their popular names of "Coneflower! or "Black Eyed Susan" . This plant I'm trying to identify has no raised central cone & it isn't black or a dark brown either. Anyway thanks for trying.

The common name for Helianthus Lemon Queen is Perennial Sunflower!

I have these too Balc, they'd take over the garden if I let them. Jerusalem artichoke rings a bell from somewhere....Helianthus tuberosa. Sunroot....you can eat the tubers too.

We have Jerusalem Artichokes growing on the allotment but these flowers here are not those. The JAs haven't even begun to flower & they are much taller, sturdier plants! In fact I brought a few tubers home & planted them in a pot, they haven't flowered yet either.

These of yours look the same as mine Balc.....must be just the perennial sunflower, but they are a thug in my garden...I keep yanking them out, and still they come through.....:o( Mine are about 3-4ft tall.

i have a tag on mine will look 2 moz but i no it def says it a rudbecker on mine, and it looks like urs .

there is a bit of a pic on my aurgust blog 5th pic down, on the top left side .looks very much like urs . and mine is rudbecker. grows over a meter ah=nd spreads like mad.

Thanks for that Cristina. I went to your blog in August, I don't know how I missed it at the time, & found the photo in the collage you probably meant, there is fencing in the background, right? It does look similar to the photo I posted above but it isn't a Rudbeckia, no raised &/or central/dark cone. From what I could make out in your photo yours hasn't either! So not Rudbeckia!

I walked around them again today. They have grown a little taller but show no sign of getting any higher. As they reach my shoulders they must be around 5ft high. Most of the clumps are below waist hight though. Plenty of flowers reach chest high. Some of them do branch but only a few. I thought of taking another photo but in the end thought better as it wouldn't improve much on the one I posted above.

i wasent sure wot mine were but ron came to viet my garden and he thort mine ewere rudbecker , will have to take another pic , a better one lol . and google .

looks a bit like tickweed (flower), Balcony, but the leaf shape more like Rudbeckia. I have two perennial tickweeds in garden tho leaves are ferny, but suppose it could be a "weed" version

tickweeds are in the genus Coreopsis and as you say the foliage is usually ferny Tetrarch.

Thanks, Tetrarch, I've done a search for "Teekweed" &, as Sbg says, it's in the same family as Coreopsis. Although they may look vaguely similar when you see more photos you realize that this plant isn't "Teekweed".

I think it is obviously a form of Helianthus.

right got a mag to day ,and in the garden sec was these flowers lol. and yes it says they are sungold from the sun flowers type ,

Dont think they are Cristina as Dwarf sun gold have many many more petals as does the Sunflower-Giant Sungold Helianthus annuus. Still think its a Helianthus though but which one?

They are growing in lots of gardens in our village Balc.....when I get chance I'll ask if anyone knows...........

lol soz ment lemon queen lol ,i will take pic of the aticul and put on

Thanks Cristina but I'm afraid I've ruled out "Lemon Queen". See my post above from the 7th.

On Tuesday I spent most of the day in the Cambridge Botanical Gardens, (a blog, or 2 or 3!) will be forthcoming in the next week or so) & not long before I left I came across a plant of Helianthus Lemon Queen. I was fortunate enough to see a lovely plant of it & I took a photo. It looks very different from the Helianthus down on the allotment.

I also came across tickweed, again in flower & again I took a picture of it &, once again, It looks nothing like from the Helianthus down on the allotment.

Unfortunately I didn't come across a plant like ours on the plot! :-(

A week ago on Saturday (25th Sep) I again spent several hours in the botanical gardens in Cambridge &, while trying to find a few plants whose name I didn't get during my previous visit, I came across the bed where the Helianthus, Rudbeckia & Coreopsis were. I took some more photos of them & especially of Helianthus Lemon Queen, this time without the blurring of the first photo I uploaded. It looked really spectacular from a distance as well as close up!

Still haven't identified ours yet! :-((

Your Helianthus looks similar to ours, but there are so many varieties native to the USA that it makes identification almost impossible. It's been in our garden for at least since the 1960s; it doesn't make tubers, which rules out the Jerusalem Artichoke, or seeds, and spreads by underground shoots just like Lemon Queen. Ours grows to 6ft in height. Although I've seen this variety, whatever it is, in a few gardens and a park in London, I've yet to identify it. I'd love to have a DNA analysis done on it just to give it a name!

Thank you Collins for your input on this flower! Even after 10 years I've not identified it other than its some form of Helianthus!

I haven't either Balc. It's a rampant strain, I have to keep it in check. I have Rudbeckia lancianata growing by it and they make a lovely show end of summer.

Thanks, Janey! I still don't know what variety of Helianthus it may be but it's irrelevant now as neither Gerry nor I have the allotments any longer. We both gave them up some years ago. :(
