identification of my dahlia

[Paifu]

Hi! I'm new here Sorry, my english is very bad. I need to know the name of my new dahlia. Can you help me? Thanks.

It looks like a species rather than a hybrid but other than that.....? Is it very tall?

Hello Paifu, welcome to the forum.
 All I know is that your Dahlia is an anemone-flowered type  similar to the species Dahlia rudis but I think it is more likely a modern cultivar....
See here for some examples : http://www.dahliaworld.co.uk/anemone.htm

Perhaps this site can help : http://www.dahlia-nds.co.uk/about_dahlias/Specie_Dahlia.htm

Yes, is a very tall plant.

An anemone-flowered type. Ok. Lesley and Maggi thanks for your help.
