Four buds and a flower

This small plant with pink trumpet-shaped flowers grows in a pot in our courtyard. We bought it 2 years ago and it's flowered non-stop since then. The nursery label called it Dipladenia. When I checked that with Google Lens just now I was told its botanic name is Mandevilla. The best explanation I've found online is this:

Since the early 1900’s, when these plants became popular in Europe, the larger growing varieties were called Mandevilla and the shorter, bushier types Dipladenia. Now, however, botanists have reclassified them all into the genus Mandevilla - from the website of the Hyannis Country Garden in the US.
