A pretty Weed but of a plague

After I posted this picture I found our that this plant is a great plague. I advise to google it to find out. the name is I've no name for it. On our last walking, Grace and I ...or I should rather say I spotted the plant on the left, took a picture of it and a bit later Grace saw the one on the right deep down the embankment of the East Holland River.

I added both pictures into a collage so you can see them together.
Please let me know if you can identify and name this plant.
Thank you and also for commenting on my pictures.

It looks ``Berenklauw`` Heracleum sphondylium to me. Take care and do n`t tuch them. They are a plauque in our country . Tutching the plant can gives you burning wonds ( for sure I need a pic. of the leaves.)

Good capture. Best to look but not touch when the plant is unknown.

@grannysueFerry @pyrrhula a friend here on 365 gave me the name and I googled it and found out it's a real bad plant. I believe in English it's called hog weed and one shouldn't go near and NOT touch it.
