I grew this plant from seeds labelled Centaurea montana, which is now accepted as Cyanus montanus. It is finally flowering this year.

But now, when I went to try to positively ID I noticed that I couldn't find any pictures of the plant showing leaves like this one has. Maybe because its a young plant?

So hoping to get a positive ID.

The flower looks more like cornflower to me.

Those leaves look less like mine than the C. montanus.
Another look at the flower ~

It looks like I'm probably growing Brown Knapweed. Hoping someone can help me confirm?

This is what the newly emerging leaves look like this year.

There are black, brown and spotted knapweed photos on the internet. The first year leaves vary.

Thank you, Greene, I'll keep looking.

The plant has been growing in a smallish pot for its entire life. It's really small, maybe one foot tall but that might be due to the pot size.

It's a tough plant but hasn't acted aggressive at all so far, same little plant.

I'll probably add more pictures again this year when it blooms...

The plant is starting to flower. Although it does look much like knapweed, I'm still not finding a good match...
