As you’re planning your vegetable garden for this year, you’re probably thinking seeds, seeds, seeds. But not everything in the garden needs to begin with seeds. In some cases, plants started by someone else are a convenient or even economical choice. And some crops, like potatoes, are grown from last season’s tubers rather than from seeds.

Here are some crops you might consider giving a little head start by purchasing plants, tubers, bulbs, etc. Most of these will also be available in local garden centers in the proper season, but if you order them from seed companies now, you will have a much wider choice of varieties, and they will ship at the right time for planting.
