Growing around 30 to 90 cm high, the slowly-spreading, fast-growing welsh onion plant features white flowers and strong-flavoured evergreen leaves. It has elongated, underground bulbs, which are not much thicker than the plant stem. In fact, some will classify it as bulbless.
Rising out of the basal foliage, the blue-green stalk is hollow and leafless. At the end of each stalk is an umbel containing small, yellowish-white flowers.
