Cakile maritima is an annual succulent with a slender or stout taproot and branched, prostrate or ascending stems that bear lobed, green leaves. The stems can grow up to 18 inches (45 cm) long. Leaves are fleshy, alternately spaced on the stem, and different from the top and bottom of the stem. The lower leaves are obovate or oblanceolate, while the upper ones are oblong.
The flowers are up to 0.6 inches (1.5 cm) in diameter, have five petals in shades of white, lilac, or purple, and appear in summer. The fruits are siliques in an oblong shape, green maturing to brown, and contain two yellow or brown, smooth seeds.
It is grown as an annual plant, so it has no USDA hardiness zone.
How to Grow and Care
Searocket grows and exists in the sandy soil closer to the ocean than the beach grass. Growing Searocket prefers sandy conditions. As a succulent, the plant holds water, making growing Searocket even easier.
When growing Searocket, don't include it as part of a vegetable garden. Companions for Searocket cultivation must be of the same family. If the Searockets detect roots of other plants close to it, an "allelopathic" action occurs. Searocket releases a substance into the root zone that stunts or otherwise deters plants of other types.
Searocket puts a long taproot into the soil and does not like to be moved. Start it from the double-jointed seed pods when they appear on the plant and mature, following the small purple blooms. This taproot makes the plant an excellent choice to hold and stabilize sandy soils that may be eroding.
