I think all I have to add since I first asked is this response from Jerry Lehman:
I am the originator of Deer Magnet and Deer Candy. Deer Candy is mid to late season excellent fruit for both deer and human. Here in Indiana it drops the fruit from October into November. The problem with most very late ripening virginiana varieties is they retain their fruit rather than dropping it, much to the joy of birds. Deer Magnet typically holds its fruit then drops it around December 1. Rosseyanka (Russian Beauty) for example here in central Indiana holds its fruit until December 1, slowly ripens it but drops only a few. You should see the starlings in that tree in December. The downfall of Deer Magnet for human use is the small size and large number of seeds, but the deer don’t care. Early Jewel (Claypool’s CV H-118) Deer Candy (CV WS19-10) and Deer Magnet (CV 100-29N) are recommended for deer hunters who want to plant trees near their deer stands to attract deer. Early Jewel begins dropping its fruit September 1, Deer Candy begins dropping October 1 through November and Deer Magnet extends the fruit drop period Into December. These are averages here in central Indiana and depending upon summer weather conditions can vary as much as 2 weeks. The picture was taken February 2015 under the Deer Magnet ortet where the deer were still coming back and pawing to find fruit. They were not pawing under any other trees. All 3 can be purchased from Cliff England nursery.
