That is a classy plant Charlotte. Quite possibly it has a name, quite possibly it is one nobody got round to putting a name on
Many of the named varieties are chance seedlings which inherited excellent growing habits, many un named varieties have yet to be noticed...
It is surprising how many un named varieties there are out there, here's one I came across in a garden of a long forgotten and abandoned property in Cornwall, England. It thrives in cool English Summers, and brutally hot Carolinas...
