Sea Rocket is a slightly bushy, medium-sized annual. The flowers are lilac to white and have four petals; they form a relaxed cluster of four to six blooms. The leaves are unmistakably shiny, fleshy, and deeply lobed. The stem is prostrate, with a tap root that goes down a long way for water, for this is a plant that grows on sand and shingle above the drift line.
Sea Rocket is found round the Irish coast, more commonly in the north and east. The name Cakile is said to derive from an Arabic word for the plant, or one similar.
Flowers bloom from June to August.
Sea Rocket grows round the Atlantic coasts of Europe.
