Could someone help, please?

I couldn't place it any closer than a lamiid, so I fed it into PlantNet
Identify. Its top result is Caryopteris x clandonensis, which looks a
reasonable hypothesis. The next two results were Vitex agnus-castus,
which has palmate leaves (not shown in PlantNet's dataset) and Hyssopus
officinalis, which lacks the fimbriate labellum. After that we get low
probability obviously wrong suggestions of Phacelia tanacetifolia,
Mentha pulegium, Mentha cervina, Succia pratensis, Mentha longifolia,
Hebe salicifolia and Veronica spicata.

I think I'm reasonably confident that it's a Caryopteris, and the hybrid
is the dominant taxon in horticulture.

I also thought of Caryopteris when I saw the OP's photo. But it also
seemed that it didn't really look quite like x clandonensis itself, as
the leaves seemed a little too narrow. Having another look, I wonder if
it could be Caryopteris x clandonensis "Dark Knight". See photos at
https://www.gardenersworld.com/plants/caryopteris-x-clandonensis-dark-knight/
and

FWIW, I grow both /Aloysia citriodora/ and /Vitex agnus-castus/, and
it's neither of those.
