St John's wort, sealfheal and one completely unknown any ideas?

[awarner]

Hope I can get some help/confirmation on the following
First off is what I believe is slender St John's wort but it does not have the orange tips, the reason I think it's the slender due to the asymmetrical petals and the leaf structure plus it was quite low growing les than 30cm



The next one I presume is selfheal, as the flowers are the same from other examples I have seen but the flower terminal head is green and not dark?



Finally I have no idea what this plant is, I am assuming it may be a garden escapee, unfortunately I have just missed the flowering going by the closeup.



Once these have been identified my total count for trees and plants will be over 87.

You are correct on the first two, the third is wood spurge (Euphorbia sp,)

Cheers for the confirmation, but the wood spurge does not look like any I have seen in books or the web?

Third one is tutsan

Third one is tutsan

You are correct. Its a Hypericum

Thanks, on another note There are quite a few patches of Enchanter's Nightshade but there is also another very similar looking plant that I missed the flowing of but presume it was around April time?
So I'm guessing this may actually be Dogs Mercury?
