|Description||(formerly classified as Allium cepa var. viviparum, bulbiferum or proliferum) is a cross between Allium cepa, the cultivated onion, and Allium fistulosum, the Welsh onion. It gets its common name from the way it â€œwalksâ€ across the garden. Instead of flowers, this plant produces topsets, a cluster of bulbils, at the top of the stalk where the flowers and seeds would normally be. The stalks eventually flop over from the weight of the bulbils (if not harvested) and replant themselves, thus beginning their â€œwalkâ€ across the ground.
