Growing perennial vegetables can mean longer harvest periods, less maintenance once established, and even improved soil structure. But selecting the best ones for your grow zone and conditions is key.

“When selecting perennial vegetables for your garden, consider factors such as climate compatibility, space availability, and personal taste preferences,” suggests Brad Addy, greenhouse and QC manager, Park Seed. He says you’ll want to choose varieties that will thrive in your growing conditions—specifically keeping in mind the amount of space you’re working with as some perennial veggies are vigorous spreaders.

From artichokes to chives, and rhubarb to leeks, these are the perennial vegetables you should consider adding to your home garden.

Benefits Of Planting Perennial Vegetables

Instead of opting for a one-and-done harvest, perennials come back year after year—no replanting required. This comes with some benefits, Addy says. “Perennial vegetables often have deep root systems that help prevent soil erosion and improve soil structure, making them environmentally sustainable garden choices,” he explains. “Also, they typically require less water and fertilizer than annual vegetables because of their established root systems and longevity.” You’ll also benefit from less maintenance than annual vegetables once established and longer harvest seasons, which means more time to enjoy your garden’s bounty.
