This was growing here and there at the upper tide line of Puget Sound (Deception Pass State Park). I usually take photos then check my field guide for ID, but can't find this one. Anyone recognize it?

Maybe a Cakile, or Sea Rocket. Not sure which one though.

Yes, that looks right. Seems I have the choice of either C. edentula or C. maritima and I'm not finding anything very clear on how to differentiate between the two. Most range maps put C. edentula where I was, although hard to say when they were last updated. I would also rather have it be C. edentula which is native rather then C. maritima which is introduced - but that's just me. In any event, now I know what sea rocket looks like.

I agree it is Cakile and they are edible. http://www.eattheweeds.com/the...
Here is some ID info.

Thanks Horntoad - per your site, I lean toward C. edentula (leaves not heavily toothed) over C. maritima (deeply lobed leaves tinted with magenta). ??

After comparing many photos and range maps, I am going with C. edentula as a final ID. Thanks for all the help!
