We cook with green onions (aka scallions) a lot. Every week or two, in fact. A couple of weeks ago, my hubby ran across
this article that said you could regrow them with nothing but some water in a jar. We thought, "No way! But if it works...." So we tried it. And it works!
After we used the green part of the onions for a recipe, we stuck the ends in a glass jar (that we would have otherwise recycled) and filled the jar with water. At first, nothing seemed to happen, but then we noticed that the roots were growing like crazy! Once they had grown out into a swirly, twisty mass, then the green tops began to grow.

Some of the shoots we'd cut just grew up taller, and new shoots joined them. After about 10 days, they were as tall as they'd originally been when we bought them, and they stopped growing. We started another jar in the meantime, which also grew like mad. We harvested the first batch this weekend, and what do you know? Just as tasty as could be! In fact, they were a bit stronger than when we get them from the store, probably because we could use them fresh instead of after they sat in a truck and the store for several days.

Because my husband is both thrifty and a bit nerdy (such a sexy combo, do you agree?), he did a bunch of math and figured out that with the cost of green onions around here, assuming we harvest them once a month, at current interest rates, an investment of $0.12 (for the water) for one jar of green onions would yield the same rate of return as putting $3,600 in our savings account. And hey, who doesn't like saving money, right? The jarful we harvested this weekend is regrowing again. Who knows how often we can get new growth from the same batch of roots, but we shall see!
(Edit: You need to leave a couple inches above the roots intact so they will stand up in your jar. We stop cutting ours when the stalk goes from green to white.)
