A close cousin of European Searocket, American Searocket also grows here on the North Coast. In fact, the two Searockets have been a bit haunting this summer becuase here similar, but just different enough.
The first one I identified was European Searocket, but for a few weeks I was going with American Searocket. Once again, the leaves were the differentiating feature. Cakile edentula has thicker leaves that are more oblong with random lobes.
Today, I found both growing together and finally feel confident in my identification of American Searocket. Check out its seed pods.
In the image below, the right side is dominated by European Searocket, while the left side is dominated by American Searocket. Note the difference between the leaves and the thickness of the stalks. American is thicker — typical. 🙂
Between the two, European Searocket seems more willing to flower, but American Searocket seems “happier” in the sand.
