Can anyone identify this plant please?

They look like Phlomis. A tall plant with yellow round flower heads along the stems.

They look to me like the seeds of Jerusalem Sage (Phlomis). I've never seen it growing wild but what you have might be an unremarkable relative... (it can't have been very noticeable if you didn't see it in flower)

Sorry about the enormous link

Thank you both. I don't 'do' yellow flowers except in Spring, so the lilac one would be lovely. I will be able to find homes for them if they are yellow. The verge contains several garden plants like Euphorbia, Buddleia, Verbascum and Stinking Hellebore, often seen in the wild, so has possibly had garden waste dumped on it at some point.

Phlomis.. probably russeliana.. fabulous plant.. bees love it!
From your description of its 'neighbours' you are probably correct that someone has dumped unwanted garden plants.. so bad for nature!
Euphorbia in particular can spread like wildfire , choking out all the native species

I agree, phlomis.

There’s an App called PlantNet. Useful to identify plants but you’ll need to have a plant with leaves for it to have enough data to work

LeslieL you do have to pay eventually for PlantNet.

I thought they might Armeria aka thrift. That usually has pink flowers though...

Phlomis/Jerusalem sage

I immediately thought of phlomis and then saw that other posters had suggested it as well. Hopefully we are right🤞.

Phlomis my bete noir. It can take over and be invasive.

If you ever want to identify anything then just use Google lense

Phlomis has over one hundred species .
It's attractive to bees and not dangerous to dogs .
Some species have very useful medicinal properties.
They prefer dry conditions .
I don't grow it at the moment,but might in future in a dry border .

When?
I've had it for ages and not been asked...
Is it according to usage do you know?

I thought it was a "Citizen Science" type thing.

Yes, Phlomis. It's a marvellous, interesting plant. The insects love it & it flourishes in my dry border next to a greedy privet, its beloved by insects too. 🌻🌷🌸
