Are You Growing Any of These Nutrient-Dense Powerhouse Vegetables?

Did you know that some of the most nutrient-dense vegetables—the so-called powerhouse vegetables—are also the most cold-tolerant?

They’re all cruciferous vegetables or leafy greens, and in most hardiness zones, you can grow them all winter long without a greenhouse. You’ll be surprised at which vegetable earned the highest ranking!

Growing Powerhouse Vegetables

The top 15 plants on the PFV list are extremely cold-hardy, and you can push their limits in winter (in USDA hardiness zones 5 and above) by growing them under a simple low tunnel covered with midweight frost cloth.

Watercress, which tops the list with a nutrient density score of 100, is actually a perennial in zones 6 and above (possibly zone 5 with winter protection).

Nutrient-dense chives, which also made the list, are a must in every perennial herb garden.
