Nice idea but alas too late.There are already two entries in the Register – by Guy L Wilson pre-1934 and WO BAckhouse in 1956. Though I do not know if either flower still exists the name cannot be used again under the rules of the International Nomenclatural rules..
I too like the robin, we always have a few in the garden in winter, then they fight leaving only one pair.We once had one that came to hand for crumbs, much to the delight of grandchildren. I’ll try to find a picture but it may have been before 2005 when I was still using film.
The English robin and the American robin are not the same bird. However, there is also already a daffodil named ‘American Robin’, a 6Y-O registered by John Reed.
