Sport or reversion?
My last post about Gypsy Rose got me wondering how you tell a sport from a reversion that has the same/similar coloring?
For example- the gypsy rose in my other post has a green division that could be a reversion to its original parentage several generations back (Fortunei Hyacinthina) or it could be a named all green sport called "let me entertain you". I also have Alex Summers that has thrown off 2 all yellow divisions- if I consider it a reversion is Gold regal and if its a sport it summer olympics.
So for my stupid question- how do you tell a sport from a reversion when they are of similar color?
