Asparagus maritimus

Asparagus maritimus is a perennial in the asparagus family, Asparagaceae. It grows to about 2 feet [0.6 metres] tall. Its native range lies around the Mediterranean and southern Europe. Records include Spain, France, Italy, Greece, Albania, and former Yugoslavia. It also occurs in southern Ukraine, Crimea, and Morocco. Its range includes the islands of Corsica and Sardinia. The RHS does not list it as native to Britain or Ireland. In the wild, it grows in sandy ground, mostly near coasts.

This species suits an open site with plenty of sun. Plants For A Future states that it cannot grow in shade. It accepts light sandy soil and medium loam. Good drainage matters, and soil may be dry or moist. It tolerates mildly acid, neutral, and mildly alkaline conditions. It can also withstand exposure to coastal weather. These traits make it an option for open coastal beds. Yet its tolerance of cold remains unclear. Plants For A Future has little information on its British hardiness. It suggests outdoor growth may be possible, based on its range. That suggestion does not establish a firm hardiness zone.

Male and female flowers grow on separate plants. A single plant cannot fertilise itself to produce seed. Grow both sexes if you want to raise seed. The supplied sources do not give a flowering season. They also lack species-level details on flower colour and fruit. The RHS describes leaves and stems for the wider genus only. Those details do not establish this species' appearance. Young shoots and stems are listed as edible parts. Plants For A Future gives edibility a low score. It suggests cooking the shoots like asparagus, but provides no confirmed preparation method.

Plants For A Future describes raising this species from seed. Soak seed in warm water for 12 hours before sowing. Sow in spring, or under glass when ripe in early autumn. Germination takes about three to six weeks at 25°C. Move seedlings into separate pots once large enough to handle. Keep them sunny and under glass through their first winter. Set them out in late spring or early summer. Division is another option as spring growth begins. The source lists no known medicinal or other uses. It reports no known hazards, but this does not prove safety.
