Species with which Perforate St John's-wort (Hypericum perforatum) interacts

There are some leaves on the extreme left of the picture which appear to be ragwort, but the yellow flowers dont look like ragwort to me. Am I missing something here Ann? Could you explain your ID please? Thanks.

Well, not sure I can,being a very green novice, I just thought it looked like a ragwort but looking at your identification of St John's wort that definitely seems to be correct. Thank you

Sorry. I was just interested

Sorry. I was just interested in case you were showing an interesting variant or something. However 'green' you are - I'm much greener when it comes to plants! I'm trying to get to grips with basic botany and this did spur me to look these sp. up, so thanks! I think I had assumed, because you have a high rep., that you were showing something which might trip a novice such as me up. If my previous comment sounded a bit ratty (it certainly wasn't meant to!) its because plants confuse me.. As soon as I think I've nailed one, something comes along to convince me otherwise! I thought this might be such a case! Thanks for clarifying.

No need for apologies. I'm finding all this is an exciting learning curve.
I think I have a higher spec because I have contributed many photos. I have certainly come a long way since I started.
And so will you

other St John's worts...

I'd agree it is a St John's wort, but I wouldn't like to say for sure which one - last weekend we found three different ones (one being 'imperforate St John's wort!) at the same site, and we had to look at the shape of the stem, 'perforate' marks on the leaves, and black dots around the sepals to work out which was which. Though in the past I'll admit I've more or less assumed that most St John's worts are the perforate one.

It's very satisfying to find different ones, and begin to get a sense of 'it looks a bit odd' for the commoner one.

Good hunting!

(By the way, it might be worth editing the title, which still says ragwort, to avoid confusing others new to plants?)
