There are certain traits that are very particular to each taxon that are important horticulturally and until the hybridization records indicate parentage at the subspecific rank, things that breed this different should be named different- HOWEVER, where do we draw the line???
Good point. In terms of what is horticulturally significant about the plants and the hybrids produced from them it is useful to maintain the distinctions even if prevailing taxonomy doesn't agree. Taxonomy and horticulture are distinct endeavors that do not need to agree on what is important.
'Species' is a concept we try to impose on the real world because humans like to put things into neat categories, and a valid species is whatever someone wants to define it as, within the formal requirements, and does it persuasively enough that others agree. There's no way it can reflect the real world diversity of all the related plant populations out there. There are almost always several levels of lumping or splitting that could make sense and be defended. No scheme is inherently right or wrong, but is it useful?
