Wild asparagus (Asparagus acutifolius) is an evergreen perennial plant belonging to the genus Asparagus. The Latin name acutifolius of this species, meaning "thorny leaves", derives from the characteristics shape of the leaves, a quite common feature in the typical plants of the Mediterranean. Asparagus acutifolius reaches on average 30–70 centimetres of height. The stems have much-branched feathery foliage. The "leaves" are in fact needle-like modified stems. The flowers are bell-shaped and in small clusters, greenish-white to yellowish, 4–5 millimetres long. The flowers are dioecious (on each plant they are only male or female).
In some Mediterranean regions flowering occurs in late Summer from August through September, often after heavy storms. In this case the small green (black) berries with 1-2 seeds, 5-6 millimetres of diameter, are fully ripe in winter.
