Walking onions are tough perennial onion plants!
In spring, a delicious green onion emerges. As summer progresses, the top of the onion stem forms a flower head of little onion bulbs! When bulbs form at the end of a stem, they are called bulbils.
Eventually, the weight of the onion bulbils becomes too great for the stem to stand upright, and they fall over! From there the onion bulbils root and a new group of plants will form, thus walking one complete step forward!
Order bulbets to propagate your own plants! Simply plant them in a little soil and watch your walking onions grow! They can be store dried over winter to use to propagate in spring. They will also overwinter in a garden bed just fine. They are very tough and forgiving propagules.
Plant walking onion plants shallowly, cover about half of the “onion”. More coverage won’t hurt.
Growth Parameters:
Expect an herbaceous garden perennial growing to about two feet tall. Clear a little space around the plants for them to fall over and spread!
