There is ...

... a white-flowered species (Petasites albus). I can't tell from this photograph which this is.

Realy?, ill get more photos

Realy?, ill get more photos to help make a positive ident, are there any definitive features I should look for other than flower colour?

The leaf shape is different ...

... but as leaves are not yet present that doesn't help. I did look in Stace and Streeter to see if there were any floral features other than the colour distinguishing the species, but didn't find anything. That doesn't mean that there isn't anything - most floras give enough differences to identify plants, rather than full descriptions.

Your plant does look rather like photos on the web labelled as Petasites albus. However both species have separate male and female plants, which is a confounding factor when comparing photographs.

So looks like we need to wait

So looks like we need to wait for the leaves, the tension is mounting :-)

I've had a look at the ...

... BSBI maps, and this isn't a known site.

Pardon my ignorance, im new

Pardon my ignorance, im new to the site, but would that likely suggest a white form of hybridus?

Not really

Since we have an expert telling us that it's Petasites albus (I don't know the plant, which is why I wasn't confident enough to call it myself) what it probably means is that the Derbyshire recorder would like to know about it.

There are about 4 known sites for the species in Derbyshire.

as it appears to be growing

as it appears to be growing on or close to the Chatsworth Estate, it may well have been planted or an escape. Leicester Botanic Garden use to have P. jap. & P. albus growing in adjacent flower beds

It is growing within the

It is growing within the pleasure grounds so could well be an escape even though its not cultivated today, im working on a wildflower catalogue as a continuation of a project I did when I was a student gardener so new finds are quite exciting, ive had to re-define the parameters to what qualifies as a wildflower as with the plant above inten.tional introduction is always a factor. Ill get more photos today or tommorow but perhaps we wil have to wait for the leaves, thanks for the help so far its much appreciated guys.

Just an observation but while

Just an observation but while driving round the gardens today I noticed that none of the regular Butterbur is anywhere near flowering, I looked in a few of the ussual places but nothing even breaking through the soil yet, so it would appear that the white one in my observation is much earlier ( its not in a particularly sheltered or sunny spot) , would this perhaps suggest that it could be a different species maybe?
