Most of the corn has put on tassels now. I have to take a trip up the ladder to get a measurement, but some are at least 16 feet high, if not taller. The person who gave me the seeds said they wouldn't produce ears with silk, but some ears have silk, while others don't. The ears are getting very long. Some look about 2 feet long. If you look just above the tallest plume of the red amaranth, you can see an ear of corn above it.
