IF it was a Burpee product and it was purchased at Walmart it was Ruby Queen.
There is another called Ruby Jewel but as with Ruby Queen this corn genetically is owned by the seed company that developed it.
There are tests that can determine is a corn is just another corn repackaged.
These test have been used successfully by seed companies to sue, and win, in court where farmers simply saved the seed without paying the company for using their seed.
These seeds are patented and if Walmart or anyone did that and got caught the courts have handed out very stiff fines.
