Part of the gardener’s spring ritual is ordering seeds (here’s how to keep garden seeds fresh) or buying starts of favorite vegetables like tomatoes, peppers and cucumbers. But did you know that there are perennial vegetables you can plant once and enjoy for years to come?

You can probably guess a few of the vegetables on our list, but others will surprise you.


Asparagus lovers can’t wait to see those stalks emerge from the soil in spring. This is a relatively easy vegetable to grow. The only hard part is that you have to wait one to two years before harvesting the first spears. Asparagus grows as a perennial in USDA Plant Hardiness Zones 3 through 10 and can live 15 years or longer.

Gardeners have more success planting live crowns over starting from seed, and all-male hybrids will produce the most stalks. Plant the crowns in a full-sun spot and keep the soil weed-free and well-watered.

The tart flavor of rhubarb is a perfect foil to sweet ingredients in recipes for rhubarb pie, crumbles, sorbets and the old-fashioned drinks called shrubs.

Many think of garlic as an annual because gardeners tend to harvest the entire crop of bulbs, requiring more be planted for the next year. However, gardeners who leave a portion of their bulbs in the ground are rewarded with garlic that comes back every year. This involves harvesting garlic from larger plants while letting smaller plants die back and stay in the ground.

Garlic generally falls into two categories: softneck that does better in warmer areas, and hardneck that grows well in colder climates. Hardneck garlic plants also produce garlic scapes — the long, curling stems that can be snipped off and enjoyed for their mild onion-garlic flavor. Here’s what you need to know about preparing the soil.
