Beach plant - what is it?

[GrandmaSue]

Anyone know what this is? Seen on Felixstowe Beach in July.

I don't recognise it as one of our native shingle-plants.

Plants growing near the sea can often look very different to their counterparts inland, and there is one that often turns up on or near the sea among the shingle, and that's Shasta Daisy - Leucanthemum x superbum, that's what I think this is. It often doesn't flower when close to the sea, but has a very tough root-system and can survive in what is a very harsh environment.

It's dittander just sprouting

Was this taken on Landguard??

This may be the flower to the 'beach plant, as you can see there is a similar near. So any further thoughts? This pic was in the same place but on a bit of grassland next to the shingle.

I don't think it is the Shasta Daisy, the leaf is much thicker.

Just seen the new photo Grandma Sue has posted, pity it wasn't posted first time round, it would have helped me no end!
Yes agree it's Dittander - Lepidium latifolium.
