Synonyms:

  • Sea-kale
  • Bunias edentula Bigelow

  • Cakile lanceolata (Willd.) O.E. Schulz ssp. edentula (Bigelow) O.E. Schulz
  • Cakile maritima L. var. americana (Nutt.) Torr.

Comment:

It should be no surprise that a member of the ubiquitous Mustard family can also be found on rocky sea shores quite close to the water. C. edentula seems happy living between the rocks and enjoying the salt spray.

 

Like many other members of the Brassicaceae, in Ultraviolet light the petal veins of Sea-rocket become UV-dark. The petals are moderately UV-absorbing. The flower's throat and reproductive parts are all UV-dark. The fleshy foliage is quite UV-black. In sum, C. edentula stands out in UV even though it is primarily UV-dark because many of the rocks around it (in this location at least) are quite UV-reflective.
