Yes, its been years since I revised my personal plant logs, and in those years, botanists have reclassified and even renamed many of my plants......Im just not sure that anyone who isnt a botanist, could possibly be at fault if in the last 20 years, some of the plants in their gardens have been renamed and legally re-classified.
That is to say, "When I planted it, it was called by another name, and it was never legally restricted".
