When we moved to our small farm in Minnesota in 1994, we told our son, who was five at the time, that he could grow anything he wanted in our garden. “I want to grow bacon,” he responded. We did raise “bacon” as well as chickens that year but decided to take our vegetable garden to another level, as well. We opted to buy many of our transplants and seeds at nearby Seed Savers Exchange. This was our first introduction to heirloom seeds and the great bounty and wonderful taste that open-pollinated varieties provide. We have been disciples of heirlooms ever since.

Gardeners sometimes think that heirloom varieties are more susceptible to pests and diseases because, unlike many hybrids, they weren’t specially bred to resist these threats. This isn’t necessarily true. Heirloom varieties that are grown in the same location year after year will, in fact, naturally adapt to regional conditions, making them a hedge against pests, diseases, and changing environmental conditions. Of the hundreds of heirlooms that I’ve grown, these eight varieties have become regular fixtures in my USDA Hardiness Zone 4 garden, selected for their superb taste and ease of growing.

‘Gold Medal’ tomato

My wife, Pat, and I grow about six to eight different heirloom tomato varieties each year—from cherries to slicers to canners. ‘Gold Medal’, a fist-size, orange-red beefsteak, is my “sit-down-in-the-garden-and-eat-it-right-now” favorite. When I am able to display some degree of discipline, I eat it sliced on toast with a dash of olive oil and basil on top. This moderate-yield tomato is, for me, the singular taste of summer. Start the indeterminate plants inside, and transplant them as soon as the threat of frost has passed.

Days to maturity: 75 to 90

‘Early Scarlet Globe’ radish

‘Rattlesnake’ snap bean

This bean gets its name from the dark purple streaks on its skin, which resemble the markings on a rattlesnake (the stripes magically go away, though, when you cook them). This variety is a vigorous climber that can reach 10 feet tall, so it requires some heavy-duty support. Other than needing something to climb on, ‘Rattlesnake’ snap bean requires minimal care and has good drought resistance. The beans taste great anytime of the year. I especially like freezing them, then adding them to soups in January to get a taste of summer in the dead of winter.

Days to maturity: 60 to 90

‘Japanese Climbing’ cucumber

Last year, I picked cucumbers from this plant well into late fall. Because it’s an abundant producer, be sure to check for fruit every other day when the plant is in full production. ‘Japanese Climbing’ cucumber is vigorous with strong grasping tendrils, so I grow it on both sides of a vertical fence to keep it off the ground. You can let the vines trail on the ground, but be sure to space the plants at least 6 feet apart. The fruit is tender, crisp, and slightly tart, and it can get up to 9 inches long. Eat it raw, paired with tomatoes, or in summer salads; for a nice surprise, try it lightly stir-fried in your Asian dishes.

Days to maturity: 58 to 65

‘Jimmy Nardello’ pepper

This family heirloom originated in the Basilicata region of Italy. ‘Jimmy Nardello’ produces a steady flow of 10-inch-long green and red peppers, with the fruit sometimes developing into a corkscrew shape. A mild, sweet-flavored pepper, our family will roast it with other vegetables or serve it stir-fried. Start the seeds inside and then transfer the transplants into the garden after the last frost in spring.

Days to maturity: 80 to 90

‘German Extra Hardy’ garlic

‘Mountain Rose’ potato

Most fruit in the garden is visible for all to see, so there is something mysterious in turning over a forkful of potatoes and discovering underground bounty—in this case, a medium-size, purple-and-red-skinned potato. ‘Mountain Rose’ is a high-yielding, versatile variety, suitable for frying and roasting, and it works well in any potato salad. The tubers also retain their rose color after cooking. I plant rows of ‘Mountain Rose’ in loose, well-drained soil and cover them with straw mulch. As the plant develops, I add additional mulch for water retention and weed suppression.

Days to maturity: 70 to 90
