Hi Sparrow
Well I never .... we live and learn. I knew it was a type of Thistle but not in the way we know them.
I have a deeper read into the subject
{'source' a book I have at home and I have used my own words}
Sparrow: Thank you for the information. The seeds are sent from other places as you have mentioned Sparrow - Ethiopia.
Also Singapore and Myanamar. It is a seed grown/tried/tested in North Amercian, and it is not related to the noxious weed thistle as we know in the UK.
Nyjer is still referred to a Thistle still. It has not gone down well in some countries and some cities have tried to ban its sale.
Nyger = Nyjer = Niger = Thistle
Apparantly there where 15 types of Nyjer seed tried and tested over the years from other countries. Goldfinches, Siskens and Repolls would only touch the Ethiopian Nyjer, and the North American Nyjer. North Amercian Nyjer is supposed to be heat treated to prevent it form sprouting in North American soil. Heat-treating is also kept the seeds well for storage purposes.
So it sounds although the Nyger seed is heat treated no matter where it is from, so it should not sprout in your garden at all.
The things that we find out about bird feed.
