Looks like a cross between an Aquilegia and a Clematis !
Can't wait for a proper identification !

it almost looks like an erythronium except it blooms at the wrong time.

I was thinking Clematis, possibly something like Sir Trevor Lawrence? and flowers mid summer to Autumn.

the leaf clasping around the stem doesnt look like a clematis though.
how big is the flower. what is its growth habit?

Looks like a herbaceous clematis to me

Looks like an aquilegia to me - I had a lot of single ones last year, it often happens when they hybridise. The leaf on the stem looks right too.

Is it Passiflora antioquiensis ?

Looks more like a Clematis macropetala type to me.....the leaf too.

I still think its a type of Clematis.

A cultivar of the herbaceous Clematis integrifolia is my best guess.

I'm going to check it out Blue......you're usually right...:o)))

Definitely a Clematis....probably Clematis Hendryetta Karen....google it and see...:o)

Hello everyone! Thanks for all your guesses, but it's definitely not a clematis! believe me, I have over 80 of them, I would have sussed it! I think the erythronium suggestion was more on track. It looked more like a bulb to me. It was only about 12- 18 " tall, with lily like leaves I think and just the one nodding flower.

Well....what a surprise Karen.......but still no answer?

I'm still sure it's an Aquilegia - I have some singles like this in my garden. It has the little break points on the stem where the next flower will form. I'll post a picture of a pale pink/green one I have.

Hi Wagger, I don't think it can be an aquilegia as the flower was about 3" across, but thanks! If you have an aquiliegia like this can you please send me some seed!!

Are the leaves mottled with brown Karen?

Now that I can't tell you Janey, I can't remember...sorry!

I stand corrected - nothing to relate the scale to - the mystery deepens.

Think Wylieintheeast has it....have a look at Harvingtons Erythroniums Karen.

Leaf looks all wrong to be Erythronium to me, I'm also not aware that any cultivars flower in June ?
Plus...don't they completely die down and disappear well before summer ?

:o(

Similar flower to a Dodecatheon meadia .......but they are multi headed...........

Yes bluespruce, I think it is too large for erythronium but bear in mind that flowers can be very late up here. I have narcissi flowering at the end of May every year! However, I have contacted the garden itself and asked them to identify. I will let you all know what the outcome is...if any! The photo doesn't have a background that gives us any help either so it's not easy!

OK,friends, this is the email I received today from Steve McNamara, head gardener at Branklyn Gardens, Perth where I took the picture last June....

Your photo is a bit close, so I am not sure about the height of the plant but I think this is a plant called Semiaquilegia ecalcarata. As you can guess the plant looks like an aquilegia but without the spurs on the flower. It is native to W. China and grows in woodland conditions. You may be able to get seed from supplier or a plant from a good nursery.

Kind of him wasn't it? WELL DONE WAGGER!!! you were almost spot on!

Well, thank you Karensusan63 but I wasn't really right was I? I certainly didn't think of a Semiaquilegia - the colour of this one is so rich. I can't remember if mine has spurs on the back or not, I'll have to look later this year. Anyway, I will accept your 'well done' with a little blush, LOL

I'm glad this has been identified now :-)))
It's certainly a lovely flower !

Yes me too........good to know at last, but enjoyed all the puzzling out...:o)
