Unusual coastal forage finds

I was out along the coast recently prepping for a walk and was expecting the usual saltwater type plants to appear, but as chance would have it I came across some really unusual finds;

Tomatoes in flower! Loads of these

Wheat, been finding this everywhere too

What I think may be marrow leaves

And possibly sunflower.

I just couldn't believe these were in the sand just above the high water mark and doing well, I hope anyone else who finds them will allow them to grow fully and if so I'll report back with pics.
