Yellow Flower - any ideas please?

[glenda]

Hello, I was wondering if anyone new what this flowering plant is? It has formed a dense layer about a metre or more high. Most of it finished flowering a while ago but this picture is of some flowering now near the coast in Cornwall. Anyone have any ideas?

Hi glenda, welcome to WAB.
These yellow crucifers are notoriously difficult without being able to clearly see particular parts of the plant. Mainly the lower leaves, and a clear close-up of a seed pod.

The upper leaves, which we can see, are entire, which leads me to think it's a Sisymbrium sp.. I think I can just about make-out some seed pods closely appressed to the stem, so it could be Hedge Mustard, which usually has hairy stems, but not always.
Best I can do I'm afraid, unless you have some other photo's?

Sisymbrium luteum may be the plant.Member of the Brassicacea...

I suspect this is unlikely as it's a plant of the Himalaya's though it is certainly in cultivation.

I'm not totally convinced it's a Sisymbrium, but it's such a poor photo from which to identify a yellow flowered crucifer I can't make any better suggestions + doubt anybody could be 100% certain of its ID.

Close ups of the leaves + particularly the fruits are needed to take this further..

Thanks for your suggestions kind people... Black Mustard is a possibility but yes, a very poor picture... Thanks again
