the first one was a pretty flower and I just wondered what it was. The second looked to me to have potential as food, kinda plantain like. Both are situated "coastal" and found on sand dune.
I stand corrected on that then - I was told to be careful as it's used for medicinal purposes as well and can't be too sure what large concentrations of the chemicals it makes would do. But if you've been eating them, then I expect they're fineI think the first one looks like Evening Primrose too....Oenothera biennis (iirc)
It's edible from the flowers to the roots.
I eat the flowers in salads and the young seed pods (tiny little oil rich seeds) are quite good lightly steamed. The seeds can be used like sesames.
