Where can I find indigo plant dyes in Europe?

Question:

Where can I find indigo plant dyes in Europe?

I assume you know - there are certain plants from which a violet/dark blue dye can be made and used for various purposes including body art. Well, I usually use henna because it's easier to find, but I would definitely go with indigo if I could get some. I really don't like that pale orange colour henna turns when it starts fading.

I heard indigo is rather common in India so I was hoping someone who has some experience can help me. Is there a company that exports them to Europe? Or do I have to bring my own?

It would also be pretty useful if someone could help me with this one...
I could ask the same for indigo.
