I should probably put this in the Farm threads but I am doing my seed buying searches again along with searches, just because I can.

I like growing tall/ensilage corn and when I type in -- open pollinated silage corn -- or-- open pollinated dent corn -- I get a lot of a few places, same corn, same place in either search.
You too often have to go pages in to find some others, having to deal with sites that have nothing to with buying seed but are often telling you how to grow open pollinated corn, or some other -- you are a dork , read this -- crap, BUT today in one search I came across more than a few sites of commercial or non-commercial forums where , by accident, you find out how ignorant some of todays young farmers are, or possibly not so young that have always done the one way they were taught, about old school Open Pollinated and tall corn.
The questions they asked about OP corn , and OR Tall Corn, amazed me along with the stories told by veteran farmers who had grown it , recently or in the past decades, compared to young ones who tried it just to see.

A different kind of search but I FOUND the corn seed packets I had put away last summer and been looking for ever since.

They were way back in the rear of he freezer.
As usual I ignored my own advice not to put them where they were not seen when ever the door was opened as they would get shoved back and I would be to lazy to clean out the freezer.
Obviously , I cleaned out the freezer for other reasons and badaboom, there they were.

After having found my lost seeds, I still had the urge to order some never before breeds.

From Truelove seeds I ordered a packet of King Philip, (Yes Phil, one L like you) corn.
From Southern Exposure , I ordered one Hop McConnell Speckled Dent Corn
and A Hickory Cane Dent corn to replace the one last year that , due to weather, never truly ripened.

Do not know how many types I will plant but as I am not going to put in as many hills of potatoes as I have for the past few years, I will decide whether to put in corn because I can or put in a cover crop, radishes or beets for the soil.
Did wheat and clover once for a cover crop but that was a snafu in the end.

I know it has been a year since your post, but I just found this forum. I grew Hop McConnell several years ago and it is absolutely beautiful corn. I can't remember much more about it, but got seeds again for this year, but I may need to wait until next year to plant them to prevent them from cross-pollinating.

You see, there is another corn I definitely want to plant this year, White Nighting Milling Corn. (Photo uploaded) I grew a small test plot of a number of flour corn varieties in the garden last year, and White Nighting is the one that really impressed me. Very nice, long ears, well-protected by long tight husks, no corn worm damage. Though very tall, the stalks were very strong with excellent rooting. We get strong winds here, and they stood strong, even when I left them long after harvest. The only disadvantage for hand-harvesting was that the ears are rather high on the stalk. I'm 5'11" and the bottom of some ears were at the top of my head. One was so high I had to bend the stalk just to reach the ear! Most seeds produced two full stalks, each with 1 or 2 long ears. Hence my reason for growing out a much larger plot of it this year to get a more accurate representation of its potential, and to test results at different plant spacing. But the reason I mention this variety to you is because of your mention of silage corn. It seems to me this variety would be excellent for that. Tall, 2 stalks per seed, so lots of silage, and no lodging. I am in Delaware, zone 7a.

Though Baker Creek carried it some years ago, they are not offering it this year. Oddly, they listed it in the big Seed Savers Exchange Yearbook, and that is where I got my seeds this year. If all goes well, I'll be able to save seeds this year.

So that is why I am determined to avoid cross-pollination, and if necessary wait until next year to plant Hop McConnell. I would be interested to hear how it did for you last year.

Total failure.

For the past few years, my corn growing has suffered some serious problems.
For decades my South garden was if I put it in the ground it grew.
Starting about six years ago, my memory sucks, I started having years where corn was total failure, from a handful to zero plants out of hundreds of corn kernels planted among different varieties the same year.

Last year was one, total failure out of two plantings.
Not sure why, ground is refurbished with Sheep manure every few years.
I am starting to think squirrels are digging up kernels as if it were rabbits there would be chewed on stalks.
SO
I cannot help you at this time.
Not sure what varieties I will put in this year.

I put in three types of corn this year.
Two types I had never had before a Red, a corn supposedly from Thomas Jefferson and a Hickory Dent from seed pack ordered last year.
The Thomas Jefferson, two plants came up, the Red out of four rows , four feet long, one row came up fully the other three each had fewer and fewer.
The Hickory Cane Dent came up fully.
Now these plots went from East to West; West being best soil, never fail; East a crap shoot and never as good as the West.
As expected the East was the failure area.
I replanted the East failures digging a trench and filling it with Miracle Grow soil, planting in that and then covering with leaf mulch.
I heavily watered so by next week I should have some idea if that works.
Potatoes planted in the rest of the East are coming up; their yield will tell much also.
