About Sea asparagus
Salicornia ambigua, also known as Perennial Glasswort or Saltwort, is a low-growing, fleshy-leaved halophytic succulent resembling small, leafless branching structures. Its segmented stems can range from bright green to reddish hues, creating an interesting textural contrast in coastal gardens, rockeries, or even in pots as an ornamental plant. It is ideal for low-maintenance, high-salinity landscapes.
Native range
Coasts of North America, from Canada to Mexico
Care tips
This plant requires full sun and prefers sandy soils with excellent drainage and high salinity content; in fact, it tolerates and even requires saltwater for optimal growth. Watering should be moderate, allowing the substrate to dry out completely between waterings, but without letting the plant dehydrate excessively in very hot climates. A common mistake is attempting to grow it in freshwater or low-salinity soils, which will hinder its proper development.
