What Vegetables Are Perennials?

Plant these perennial vegetables once and reap their benefits year after year.

Rhubarb 

Rhubarb is a hardy perennial with big leaves and pink, red, or greenish leaf stalks that are used in desserts such as pies and crumbles.

watercress

Watercress is a sun-loving perennial that grows naturally alongside flowing waterways. The pH range for watercress is 6.5 to 7.5.

Asparagus 

Asparagus plants, unlike most vegetables, are perennial, which means the same plants grow in your garden year after year.

Sweet Potato

Sweet potatoes are perennial in warm-weather climates, but they can also be grown as an annual in cooler climates.

Wasabi

Wasabia japonica is a Japanese mountain native perennial brassica. Wasabi grows semi-aquatically in the wild alongside streams, with huge trees overhead providing shade.

Broccoli 

Most broccoli cultivars grow as annuals, producing a huge head at the end of the season and then dying. Try the Nine Star or Purple Cape variety.

Spinach

Not all cultivars are perennial. Try Ceylon, Sissoo, or New Zealand varieties.

Horseradish 

Horseradish is a strong, hardy perennial with a mass of green growth that is mostly grown for its spicy roots.

Tree cabbages

Tree cabbage is among the few perennial vegetables that prefer a heavy clay soil, which helps anchor this very tall plant.
