Truman Capote famously told friends that the very wealthy eat better vegetables - tiny ones. So there's another plus for gardening: It's easier to eat the way the super-rich do.
Not that smaller is always better in the world of vegetables. A cucumber picked undersize does not taste better than one allowed to swell up before harvest.
Similarly, the taste of baby carrots can't compare with fully grown ones, unless the "baby" size is how big the carrots are supposed to be when fully mature. A certain degree of maturity is needed before a carrot can store energy, which translates to sweetness, in its fleshy roots.
"Baby carrots" that you buy in the supermarket are full-size carrots cut into smaller pieces.
There's no arguing that tiny vegetables are more fun and convenient to eat. That must be what accounts for the popularity of supermarket cherry tomatoes.
The bulk of these, unfortunately, are the variety Red Cherry, which doesn't taste nearly as good as Sungold, which has a delectable sweet-tart flavor.
Miniature cauliflower is another tiny vegetable that is fun and convenient. This one tastes pretty much the same as full-size cauliflower. The way to grow minicaulis is by planting out any variety of cauliflower at a 6-inch spacing each way and letting competition among the plants keep them dwarf as they mature.
Of course, tiny vegetables' main draw is their perceived gustatory superiority. And it's true: Many vegetables are most delicate, tender and tasty at this stage.
Fine examples of vegetables that reach perfection early in their growth are zucchini and other summer squashes. You can even pick zucchinis before their blossoms have wilted and been shed, eating the tasty blossoms along with the fruit.
Every gardener knows how fast a zucchini can grow from the size of a carrot to that of a baseball bat. A few days' delay in harvest rapidly plumps up zucchinis and the wallet of any farmer who is paid for poundage. For a backyard gardener, though, frequent picking of tiny zucchinis yields better taste and keeps the kitchen from being overrun.
And then there are vegetables that take on a different character if picked while still tiny; they're not necessarily better, but they are different.
As green beans mature, the seeds within the pods expand and contribute to the flavor and texture.
When baby-size, beans are almost all pod.
Baby corn is similarly quite different from large ears of sweet corn whose kernels are plumped full of milky, sweet juice. But they're both good.
Any variety of lettuce, especially heading lettuces, takes on a different taste and textural quality as it matures. As lettuces grow up, the leaves of some varieties turn buttery.
Those of other varieties become crisp only along their ribs, and still other varieties become crispheads. Flavors may also take on distinctive qualities.
