Corn, Ruby Queen Hybrid

Short Description

Really red, really sweet.

Full Description

Hybrid SE Sweet Corn. Ruby Queen is an amazing new sweet corn with an amazing corn color-it's really red! You won't believe how appetizing a red corn can be until you see it on your plate, then bite into the extra-sweet, tender kernels. You can enjoy Ruby Queen at two stages. Pick it when it's blush-red for maximum SE sweetness, or let it ripen to full red so it can develop its rich, old-fashioned corn flavor. The meaty ears are 8" long with 18 rows of juicy, very tender kernels. Plants are 7 ft. tall and often bear two ears apiece. No need to isolate from other corns, but we suggest that you grow another SE variety with Ruby Queen to help with pollination. Ready to harvest in 75 days. Steaming or microwaving are the best cooking methods for enhancing the delectable color. As an added bonus, the red tassels and stalks make fantastic autumn decorations. Grow in full sun in rich, fertile, well-drained soil.

How to Sow

  • Growing corn is easy provided you have enough space and plenty of sun. Corn is wind-pollinated, so you need to plant in blocks to ensure pollination. You should have a minimum 10 foot by 10 foot area. The exception to this rule is ‘On Deck’ corn, which has been bred to grow in containers. If you are growing ‘On Deck’, choose a container that is at least 24 inches wide and deep and plant nine seeds evenly spaced.
  • Isolate corn varieties when recommended (Sh2s), by planting corn seeds at least 250 feet apart, or select varieties that mature at least 2 weeks apart so they will not cross pollinate.
  • When choosing a site for corn, plant on the north side of your garden so the tall plants do not shade other plants in your vegetable garden.
  • Corn is a warm season crop and should not be planted in cool soils. The non Sh2 varieties tend to be more tolerant of cool soils, but in general the soil should be about 65 degrees F or warmer.
  • Sow corn seed 1 inch deep, 5 to 6 inches apart in rows 2 to 3 feet apart.
  • Seedlings emerge in 7-14 days.
  • When corn seedlings are 3-5 inches tall and healthy, thin to 1 foot apart.

How to Grow

  • Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating.
  • Keep plants well watered during dry periods to promote uninterrupted growth. Corn needs 1-2 inches of rain per week for best production. Use a rain gauge to check to see if you need to add water. Corn is also a heavy feeder and will benefit from side dressings of fertilizer applied as directed through the growing season.
  • Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
  • Suckers tend to form at the base of the plants; they help support the stalks and make food for the plant. The stalks may have to be staked in windy areas, but in general they are self-supporting.
  • Sunflowers are good companion plant for corns. Direct sow sunflowers in rows parallel to corn rows to help separate corn varieties that need isolation from each other. Choose sunflower varieties of comparable height to the corn plantings. The sunflower border, with vibrant hues in russets to golden-yellow, will add sparkle next to the almost all-green corn plot. The ‘Three Sisters’ (corn, bean and squash) are traditional companion plantings with Native American gardeners.

Harvest and Preserving Tips

  • Ears of corn are ready to harvest about 17-20 days after the silks appear. The kernels should be firm. Open an ear and pierce a kernel with your fingernail. If the liquid is watery, the corn is not ripe yet. It should be milky. If it is creamy, it is overripe and will not taste as sweet.
  • Firmly grip the ear and twist downward to harvest. Take care not to break the plant when harvesting the first ear, or the second ear will not develop. Most corn produces two ears.
  • Store unhusked corn in the fridge and consume as soon as possible. Sh2 and SE varieties keep the longest in the fridge, up to one week.
  • Corn freezes well after blanching and may also be canned using a pressure cooker. Immature ears may be pickled.

Corn, Ruby Queen Hybrid is rated 4.2917 out of 5 by 24.
Rated 3 out of 5 by from A little let down I tried Ruby Queen this year and had mixed results. In my case, the seeds germinated unevenly, leading to some plants that were well ahead of others. Most plants grew 7-8 feet and looked great. I did not plant another corn variety to help pollinate. I think this decreased my yield as 70% of the plants had corn and some of those only produced little mutant-looking ears. Also, with most varieties I've been able to get 2 ears per plant. With Ruby Queen I got 1 ear on the plants that produced. The ears I got were nice but a little on the smaller side. I picked some of the corn a little early while it was still kind of bi-color and just developing its red blush. I did let some go for longer to develop the red color more but I think corn at that level of ripeness is too tough and starchy. My experience was that this corn was not as sweet and was lower yielding than white corn.. I may try again with a helper variety for pollination and hopefully yields and sweetness will improve.

Rated 1 out of 5 by from Poor Germination Soaked seeds overnight, planted second week of May, very shallow soil cover.. Out of 200 seeds about 10 came up. Will try re seeding, but not very impressed. Can't even find seeds that didn't come up to know what happened.

Rated 3 out of 5 by from Not Happy with Germination Rate Well, so far not excited about the germination rate at 65%. Pre-soaked the seed kernels overnight, too. Will update the review with how it handles the New York weather and the growth and taste of the corn once it's harvested. The Stowell's Evergreen Sweet I bought from a different company, on the other hand, had an 85% germination rate, and is reaching for the sky at an unbelievably fast pace! It's 3 times the height of the Ruby even though planted at the same time. That one shows promise!

Rated 5 out of 5 by from Best sweet corn ever! Ruby Queen corn is actually quite tasty and easy to grow. Just soak the seeds overnight and dry them out for a few hours before planting and you should get a great stand. Besides tasting wonderful, they are quite the attention grabber with their ruby hue.

Rated 5 out of 5 by from We LOVE it- but low germination We LOVE this corn- it is delicious and gorgeous (and keeps its gorgeous red color if you microwave it - 3 minutes for 2 ears). BUT it had a very low germination rate this year- we had to reseed it twice! We will plant it again and hope that next year the germination rate will be better! My husband is a chef (we have an historic inn) and every dinner guest who gets this corn LOVES it!

Rated 4 out of 5 by from delicious corn We had a bad season this year, almost everyone in the area mentioned that nothing grew well. This corn didn't produce as well as our yellow corn did last year and I can't say if it was the terrible season (our other plants were hit also) or the type of corn. What we did get from it was absolutely delicious. It is robust and full of flavor in a way that no yellow or bicolor corn I've ever tried is. We'll probably go with more than one variety in the future for volume, but we'll keep planting this because it's just too good not to.With fall setting on, the beautiful drying stalks with a reddish hue will also make unique decorations.

Rated 4 out of 5 by from sucess! Slightly lower production than yellow corn (I planted it with Chubby Checkers), but is sweet and tasty, and is really red. Microwaved, it stays red! Great hit at picnics. I only gave it 4 stars because I had to plant another variety. I got two years out of my seeds, and have planted the same batch for a third. Too soon to tell what this year's will do.
