Never collected seed. & do not remember seed pods. only sugestion is go ahead & plant & see what happons THEN let us know.

Wesserma, One point I would like to bring up about the USDA. When you fill out your form to obtain the seed, I recommend you list an Organization. If you put 'Wesserma Seeds' (or something like that) you won't ever get hassled. You also need to fill out the the section for intended use. Just say something using the words 'breeding' or 'research' and you are golden. Otherwise they will send you a one time only order. You'll get a letter saying it's a one time offer to gardeners. If you do it like I said, then you can get as many orders as you want. Of course, you only order one accession once, and not many times. You need to save the seed from the accessions you obtain. You can make multiple orders to get different accessions. In my expert opinion, some of the tropical corn varieties are hard to save seed unless you jump through hoops. What I recommend you do; so you are not dependent on tropical corn pimps hustling their proprietary tallest corn, is to find your self some very large temperate varieties and cross it with your tropicals. Once you can get consistent ears on your plants, then you can do selecting for taller ones. R.H Shumway has one called Goliath Silage. The current Iowa State Fair champ used Goliath to get a 18'4" plant. https://www.rhshumway.com/shumsite/shumsiteviewproduct.aspx?ProductID=16954 USDA also has some nice sized temperate corn http://www.ars-grin.gov/cgi-bin/npgs/acc/display.pl?1026853 Local name: White Dent.

Agree that they will grow in any exposure, but if you want the really big leaves, mostly shade is best, IME (a few miles north of AL/FL border.) I moved this bulb this spring from a much more sunny location where it had been for a few years and it's making leaves about 10x bigger than before. (The babies bulbs that were with it were also put in more shady locations and are all much bigger than the mama ever was in too much sun.) I also have a mini-compost pile at the base of it, and put mostly greens there, like watermelon rinds and other kitchen scraps that "melt" quickly in the heat. Next to it is a 5-gallon bucket with a slit in the bottom. I fill up the bucket and it takes a couple hours to drip out, which I try to do just before the sun hits it, so it has ample moisture during that time, about 90 minutes of direct sun. Otherwise, the leaves fall over. After they do that, they might or might not stand back up so I put a tomato cage around it. The newest leaf on this plant is about 6 ft. tall and about 3 ft. long, which is about 8" longer than the last leaf. Constantly losing a leaf is common but happens more slowly if there is ample moisture and plenty of organic matter in the soil. I usually leave the dying leaf connected but bend it back to rot near the bulb. Unfortunately, I don't usually have rain water for it, but start by dumping the water from the bucket our dog uses for his water bowl (which came from the hose the day before,) then fill the rest with the hose. With splashing and the dripping that happens before the bucket is full, I estimate it, and the other plants sharing the root space, are using about 6 gallons of water per day, some of which is probably taken by a large oak tree nearby. Just an ordinary Colocasia esculenta I got from Lowe's about 10 years ago. The leaf that is leaning out didn't seem like it would bend into the tomato cage without breaking and since it was the oldest (going to yellow and die soon,) I didn't make any effort to cage that one:

In the vacant lot next door to me the poison ivy runs rampant. The birds eat the seeds and poop them in my yard as they fly over and voila, I have poison ivy seedlings to deal with. The wind could blow the seeds over as well. I've been fighting poison ivy for 17 years now and usually get it myself at least once a year. If it blows in my yard or is pooped there, think where else it could be going. This is just one example of an invasive plant getting away. There are many other plants that do the same, including my personal "favorite" the golden rain tree. :o)
