Different Kinds Of Corn – Popular Varieties Of Corn Plants To Grow


By: Bonnie L. Grant, Certified Urban Agriculturist

Fresh, sweetsummer corn is a treat to look forward to when planning your garden.There are many corn varieties, from hybrids to heirlooms. Depending upon yourzone, there are varieties of corn that ripen at different times of the season,various colors and even sugar enhanced types. We’ll go over some of the bestkinds of corn so you can get cracking on your summer garden planning.

Popular Corn Plants You Can Grow

As you start your list of seed to purchase, deciding whichcorn plants to grow can ensure a big crop of this sweet veggie. However, decipheringthose seed catalogs can be challenging. Among all the types of corn,you will also have to decide if you want normal sweet corn, sugar enhanced, orsuper sweet corn. The choices can make a gardener dizzy. A primer on the threemain categories of corn can help narrow down the selection.

Standard Sweet Corn

This classic group is one of the most popular selection ofcorn varieties. The traditional flavor and texture simply sing “summer,” butthe drawback is that they don’t store for long. More than a couple of days inthe crisper and the sugars turn into starch. There are early and late maturinghybrids, making them a good selection for almost any zone.

These types of corn also come in white or yellow. Some ofthe standard varieties are:

  • Silver Queen – mid to late white
  • Seneca Chief – midseason golden kernels
  • Utopia – bicolor with fairly early harvest
  • Sugar Dots – midseason bicolor
  • Earlivee – early season yellow
  • Golden Bantam – heirloom yellow midseason
  • True Platinum – purple plants with white kernels, midseason
  • Seneca Horizon – early maturing yellow
  • Stowell’s – late season heirloom yellow

Many of these are disease and blight resistant with creamyflesh and standard sweet flavor and the young plants are vigorous.

Sugar Enhanced Kinds of Corn

These varieties may have up to 18 percent more sugar contentthan the standard sugar types. They hold better than sugar varieties but the skinaround the kernels is more tender and sensitive to damage. However, thischaracteristic also makes them easier to chew. These are generally planted oneweek later than standard varieties.

Some of the better sugar enhanced varieties are:

  • Sweet Riser – golden corn with early maturity
  • Legend – another early yellow
  • Sweet Ice – white corn maturing early
  • Double Choice – mid season bicolor
  • Temptation – early bicolor
  • Whiteout – midseason white
  • Quickie – early bicolor
  • Silver Knight – early white
  • Iochief – late season yellow

The ears of sugar enhanced corn store longer than regularsugar corn.

Supersweet Varieties of Corn

Supersweet may also be called shrunken corn due to theappearance of the dried kernels. There is twice the amount of sugar astraditional sweet corn varieties. Because they convert sugar to starch muchslower, they can be stored much longer. The seeds of these types do notgerminate well in cooler soils, and yields from plants are significantly lessthan sugar types.

They are also planted later in the season. The kernel has amuch thicker exterior, which makes it great for storing and shipping but can betough to eat. Common supersweet corn includes:

  • Mirai – Asian variety, midseason yellow
  • Sweetie – midseason yellow
  • Vision – midseason yellow but germinates better in cool soil
  • Indian Summer – midseason yellow but kernels turn red, white or purple prior to ripening
  • Candy Corner – early season bicolor
  • Krispy King – midseason yellow
  • Early Extra Sweet – early golden kernels
  • How Sweet It Is – late season white
  • Gotta Have It – midseason bicolor

There are many more varieties in each category, but theseillustrate some of the best types in each group. There is something foreveryone. Satisfy a sweet tooth, harvest early or store for longer. Surely oneof these will be the right fit for your garden.

How to Grow and Use Ornamental Corn for Dazzling Decorations

Rebekah started a small farm with her husband in 2016 in upstate New York, just north of the pristine Adirondack Mountains, where she grows vegetables and herbs and also raises sheep, chickens, and pigs. There’s nothing she loves more than helping others learn more especially about sustainable living as it pertains to health and homesteading. An avid cook, she works hard to grow and preserve enough food to support her family throughout the year.

Sometimes, it can be hard to justify making room in the garden for crops that ultimately are grown for aesthetics – rather than their value as edible crops.

However, ornamental corn is one of those plants that I always make room for.

I’m able to justify it to my husband – who isn’t big on plants grown purely for their appearances alone – by explaining that it can be used to feed our pigs and chickens after the growing season (and fall decoration season!) has ended. Fortunately, he now loves growing ornamental corn just as much as I do.

This beautiful crop is one that has been grown in the US for centuries – long before the land was even recognized as its own country. Here are some of the best uses for ornamental corn – and some tips on how to grow it in your own backyard garden this summer.


Parching Corn

Every elementary school student knows that Native Americans told the Pilgrims about corn and showed them how to grow it. Then, as now, corn was an essential crop and valued for its versatility. From cornflakes to corn syrup to popcorn to ethanol, the plant is woven into our modern culture as much as it was into ancient ones. This article is about another type of corn, one that is unknown to most Americans: parching corn.

What is Parching Corn?

The word parching is from Old English and means to make dry, the way your throat feels on a hot, dry day. Parching corn means not only to cook the kernels gently until they expand and soften, but in this case, it also refers to the corn varieties best suited to this treatment.

Parching corn is similar to popcorn, in that kernels pop loudly when heated. But these two types are different in almost every other way, including flavor. True parching corns are varieties of flour corns, and their kernels are soft and dry when mature. When heated, they expand only slightly, and the seed coat usually splits. Popcorns are flint corns. Their hard, brittle mature kernels explode furiously when heated, expanding in volume.

Parching corns are much sweeter and more flavorful than popcorn and don't need added oil or salt to enhance their flavor. Their sweetness and flavor develop as you chew, so munch them thoroughly. Finally, you can prepare parching corn easily in a microwave oven, then store it in a sealed container for about four months.

The Best Parching Corns

Although any flour corn can be parched, not all parch well, and most don't taste very good. White flour corns all taste bland, and yellow ones usually have a disagreeable aftertaste. Black varieties taste pretty-well, foul. All the great-tasting parching varieties are red or purple or have streaks or spots in those colors. ('Parching Black Cherry', which appears black, is actually a very dark purple.)

The eight varieties described here represent three different flavor classes. The purple ones all have flavors similar to each other but totally different from the reds, which form another class. 'Parching Black Cherry' is in the third class.

Not all red or purple flour corns are great parching corns, however. The best ones become sweet as you eat them, have tender skins, and offer delicious flavors. In addition, they parch quickly and uniformly and resist burning. Native Americans still grow these red and purple varieties specifically for parching.

The Most Versatile Corns

Parching corns may be the single most versatile type of corn. At the milk stage before kernels are mature and dry, they are as sweet as standard sweet corns, and they're very flavorful to eat from the cob or as a side dish. The ears are as beautiful as any ornamental corn, and children love both their brightly colored kernels and their flavors. You can parch dry kernels, or grind them unparched to make an excellent corn flour.

Parching corn would seem to have considerable potential for home and large-scale growers. This corn retains its freshness at room temperature for at least 3 months with no special packaging and no preservatives. Because of its long shelf life, market gardeners could sell it year-round. Possibilities abound on a larger scale, too. After parching, it could be sold like nuts or candy. Because it is so easy to parch in a microwave oven, unparched kernels could be sold in grocery stores like popcorn.

Parching corn can grow wherever sweet corn can. First, choose a variety that can mature in the growing season typical for your region. (The growing season is the time between the last frost in spring and the first frost in fall.) If you don't know what is typical for your area, check with a master gardener, cooperative extension agent, or garden center.

In hot-summer areas, short-season parching corns require only 80 to 90 days from sowing seed to full dryness. In cool-summer regions, the same varieties will need more time. Long-season varieties need 100 days or more.

To ensure good pollination and ears packed with kernels, always plant corn in blocks of short rows, not in fewer, longer rows. For instance, 100 feet of corn is better pollinated if planted in 10 rows that are 10 feet long than in 5 rows that are 20 feet long.

If you plant several varieties of parching corn in your garden, put them in separate blocks at least 20 feet apart so that each variety will mostly self-pollinate. Or plant varieties that flower at different times for example, a block of a short-season variety adjacent to a block of a long-season variety.

A little pollen from other kinds of corn won't have much effect on a block of parching corn. But the flavor and texture of a sweet or supersweet corn will be ruined if it's pollinated by the parching corn.

Grow parching corns in rows or hills, the latter being especially useful if your soil is poor, or if you want to interplant beans or squash.

Spread a 2-inch layer of compost, or about 10 pounds of a complete organic fertilizer (with about 5 percent nitrogen) per 500 square feet, over the planting area. If you live where soil is normally acidic, include dolomitic limestone if your soil is alkaline, add sulfur. A soil test is the best way to know exactly how much of either to use.

Incorporate Amendments by Tilling or Digging

In my own garden, I use a complete organic fertilizer that is by volume 3 parts cottonseed meal, 1 part dolomitic limestone, 1 part rock phosphate, and 1 part kelp meal. I apply 1 gallon of this mix to every 100 square feet when turning or tilling the soil. I often add organic fertilizer to the rows or hills when planting. Even though plants grow best in fertile soils, parching corns have deep, vigorous root systems, so they're well suited to growing under less-than-ideal conditions. Sow seeds after danger of frost has passed and soil is warm.

Before planting, putin a band of extra compost or fertilizer along the row: 1/2 gallon per 100 feet of row. Sow seeds 1 to 2 inches deep and 4 inches apart. Allow 3 feet between rows. Later, thin plants to 1 to 2 feet apart.

Space the tops of the hills about 6 feet apart in all directions. Work a shovelful of compost or a cup of organic fertilizer into each hill. On each hill, plant about six seeds 1 to 2 inches deep in a 12-inch-diameter ring, then thin to two or three plants when they come up. To interplant pole beans, plant one or two seeds in each corn hill after the corn is 4 inches high. Plant squash in their own hills between the corn or around the edges of the corn patch.

Even the smaller varieties of parching corn benefit from wide spacing, which allows their side shoots (tillers) to grow to nearly the same size as the stalk and yield good ears. Crowded plants set only one or two ears on the main stalk only.

Hinder weed growth by hoeing soil up around the cornstalk (hilling up). Hoeing disturbs, buries, and kills emerging weeds in the soil. The corn appreciates it: Plants will send new roots into the hilled-up soil. Hilling up also prevents the stalks from falling over, or lodging.

How and When to Harvest

To dry well in the field, parching corns need dry weather at summer's end. Because ears of parching corn retain more moisture and resist drying more than other types of corn do, they are more prone to rotting in high humidity. This is why East Coast Native Americans (and the early colonists) grew flint corns. Now, with heated houses and commercial drying facilities, gardeners in most regions of the country can grow parching corns.

If you live where summers are dry, you can mature ears the traditional way, right in the field. Leave ears on the stalks until kernels are fully dry. Where summer rainfall and humidity are common, the ears will likely mold or rot before they dry in the field In this case, let ears develop until they begin to dry. Harvest as soon as kernels are somewhat beyond the milk stage (when pressing on a kernel, it releases creamy white liquid) and slightly hardened. Shuck ears immediately and spread them out in a warm, airy, indoor place to finish drying.

Fully dry ears of most kinds of parching corn are very easy to thresh by hand wear soft, thin, leather gloves. Break each ear in half, twist the kernels off in bunches, and then rub the loose corn between your gloved hands to separate the kernels from the bits of debris clinging to the base of most of the seeds. To separate the debris from the cleaned kernels, pour the kernels from one container to another outdoors when it is windy, or in front of a fan. Store kernels in glass jars or other airtight insect-proof containers.

Preparing and Enjoying Parching Corn

The traditional method is simply to heat kernels in a heavy skillet over low heat. Don't use oil. Stir the kernels with a spatula as they cook. Traditional parching takes about 5 minutes. Hold a lid or grease screen above the pan to keep the kernels from jumping out. Or, instead of using a spatula, you can cover the pan and stir the corn by shaking the pan on the burner, as with popcorn. If you don't pay close attention, the kernels will burn. Stop the cooking when the popping mostly, but not completely, ceases.

Put about 1/4 cup of plain dry kernels in a single layer in the center of a microwave turntable cover with a paper plate. Much more or less than 1/4 cup of kernels microwaves poorly. If the oven doesn't have a removable turntable, put the corn in the center of a thin plate and cover with a paper plate. Don't use a heavy covered bowl it absorbs too many microwaves. Microwave on high for 3 minutes. As with stovetop parching, stop the cooking when most (but not all) of the popping is over, 1 to 2 minutes depending upon variety, moisture content, oven size, and power. Most varieties produce a delicious aroma just as they finish parching.

Uncooked kernels of parching corn don't have to be separated from the cooked batch they're soft and tasty even when raw.

Parching Corn: My Route to a New Crop

My passion for parching corn began in the fall of 1995 with Alan Kapuler, an enthusiastic plant explorer as well as research director for Seeds of Change. He had grown seven Hopi flour corns that season, and bags of brightly colored ears were stacked all over his living room, seed room, and greenhouse.

"Here, try this one," he said, carrying a cast-iron skillet full of toasted corn over to me. "Some of the varieties are pretty awful fixed this way, but my family really likes this one."

As I looked at the red-and-white-striped kernels, I thought of corn nuts, that hard, tooth-cracking snack food. I took a few kernels, but with low expectations. Surprisingly, the kernels were soft. As I chewed them, they became sweeter, then developed a delicious nutty, rich flavor, unlike anything I'd ever eaten.

I took some corn home and worked out ways to parch it in a microwave. As I ate the delicious treat, I realized this type of corn could become a major grain staple in my diet.

I went to my own collection of corn seeds and began parching samples of many varieties. I soon discovered that the best parching corns were all soft, or flour, corns. Some flint corns, when parched, produced something similar to corn nuts. Other flint corns only partially popped and parched, or didn't cook completely when parched they were inedible. But all the flour corns parched to make soft, edible kernels. Among flour corns, some parched much more quickly and uniformly than others, and flavors ranged from wonderful to terrible.

My next step was to call the seed companies that had the best selections of flour corns, various members of Seed Savers Exchange, and Mark Millard, curator of the country's biggest corn collection, the USD collection in Ames, Iowa. No one knew much about which varieties would be best for parching, but everyone was eager to help. I soon had samples of about 200 different flour corns to evaluate. Among them I found eight truly superb varieties. However, only three were available commercially.

In the spring of 1996, I located potential corn growers, supervised growing of seed corn, and collaborated with seed companies to add the new varieties to their catalogs.

Now it's up to you to try parching corn. Taste it, and see if you agree with me about this crop's potential.
