Can anyone tell me what they call this plant

[ottosump]

Is it a weed or a flower, a friend told me its a Rananculos 'crows foot' but I've googled and can't find a similar one.
Kind regards otto Media URL: http://a2.sphotos.ak.fbcdn.net/hphotos-ak-ash3/553476_4070329120388_1347174209_33701356_553280629_n.jpg

Sorry the link doesn't work

It's a Californian Poppy

[boxtops]

it's not ranunculus, that looks quite different http://en.wikipedia.org/wiki/Ranunculus

It's a Welsh poppy...they do self-seed like weeds! :o)

[boxtops]

ditto for the Californians, robinia - my garden is full of seedlings just like this one!

I thought Poppies were Red.

[Robinia]

but the californians have feathery leaves don't they?

[daffy654]

Definitely a Welsh Poppy.

[boxtops]

Perhaps mine are indeed Welsh poppies then - I didn't plant them so they don't have a history, they just appeared!

[daffy654]

Californian poppies have a different centre to the Welsh ones, they are a slightly darker hue too.

Wow, thanks for the answers guys, 'Welsh' it is then, must be hardy critters to exist in a baron wall.

So that's what they are! They come up all over my garden, and are so deep-rooted as to make digging them up a pain. Fortunately, I've found that Roundup does the business.

Meconopsis cambrica same family as the Himalayan blue poppy
