Short Description

Garden asparagus is a perennial plant that can grow up to 1.5 metres in height.

Its leaves are small and scale-like.

Young shoots grow from underground roots. They are fleshy, whitish or pale reddish covered with tight scaly leaves. These shoots are cut young for eating. Later, these shoots develop into a green, broom-like stem with thin, needle-shaped leaves.

The flowers are drooping and white to greenish. The corolla has six petals and is bell-shaped.

The fruits are bright red berries.

In the city

In town, asparagus often grows in verges or on embankments. It prefers dry, moderately nutrient-rich sites with sandy soil.

As a vegetable, it was cultivated in many urban gardens and fields and has often gone wild.
