There was only one.
One, huge plant that was growing among young pine trees, grasses and some other bushes that usually sprout in the fields that are not taken care of.
I didn't write it's full name on purpose - I am having some problems getting full ID for it. There is a few types that look extremely similar: Verbascum phlomoides, Verbascum phlomoides and Verbascum phlomoides.
Though I am almost sure it is not the last one as it seems less popular in Europe. So we have two left :)
Commonly known as Mullein, it can be found throughout the Europe. Blooming start around May and last until about October depending on the region. It is a very resilient plant and will grow in poor soils with little rain.
You an see on the photo below how tall it is. The tallest stem was about my height. The leaves are huge too and stay loser to the ground.
The yellow flowers will open on the stem continuously. Lower it was already producing seeds, while the top was still growing with a bunch of new buds waiting to open.
The photos were taken in September in Poland and I'd say it is still in bloom right now.
A I was editing the photo I remembers that I saw a flower like that before. And nor in Poland, but in Portugal (and show some years ago).
Here it is:
This is verbascum sinuatum - smaller plant with some purple in the center. The flowers are about the same size, but the stems and leave are not as big. The temperature in summer is much higher and with hardly any rain they are often the only flowers in bloom among all dried up grasses. That's how though they are :)
This is a graphic for Verbascum phlomoides from 1887.
