What is that wonderful succulent yet scrubby-looking green plant we see growing on our local beaches? You are most likely looking at American Sea-rocket (Cakile edentula). Named for its rocket-shaped berries, Sea-rocket is a native annual. It grows in dry sand and is pollinated by beetles, moths, butterflies, flies, and bees. The edible flowers and peppery, succulent leaves, which taste somewhat like horseradish, attract myriad species of tiny insects as well.
Sea-rocket reseeds itself each year all around New England beaches and thrives in the poor medium of dry sand, above the high tide line. In springtime, along the Massachusetts coastline, you will see tiny shoots emerging and by early summer the multi-branching plant can grow two feet wide and equally as tall.
Throughout the Piping Plover’s time spent at Good Harbor Beach, Sea-rocket is an important plant, providing shade on hot summer days, protection from the wind, and attracts a smorgasbord of insects that both the adults and tiniest of chicks depend upon for their diets.
Piping Plover chicks and adults forage for small insects at Sea-rocket.
Sea-rocket growth progression-
The third photo was taken during the second week of July. Look how beautifully the Sea-rocket is growing in the roped off area. The fourth photo shows the same area after the PiPl refuge was dismantled and the Sea-rocket raked over.
