This aquatic mint produces light violet flowers and resemble to Mentha aquatica L.
The experts may please suggest the correct ID.
I think yes.
Is it cultivated ?
Not sure but probably introduced. I found it along a stream draining into a lake at 1400m.
I feel closer to Mentha aquatica L. var. citrata (Ehrh.) Fresen. as per the following:

…, I am not exactly sure where I got this plant from as it was growing at home in one of the pots as an uninvited guest. I clicked it before I left for the trip and when I got back, my mother had emptied the pot for another set of plants so I couldn’t take a closer look.
The links you have provided look spot on for Mentha x piperita! But how is it different from the one in the last link?
I do not know, please check – http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=120248#KEY-1-7
Fits with Mentha spicata– leaves petiolate, calyx teeth triangular, corolla purplish as opposed to leaves subsessile, calyx teeth linear and corolla white with red tinge on the lobes in Mentha x piperita. Please validate.
I am none to validate any id. Instead, I write what I think.
First, let me check if a hybrid can produce seeds, and if those seeds can be fertile. FoP says Mentha x piperita L. is sterile. PFAF informs M. x p. vulgaris L. is a natural hybrid and do propagate by seeds. I cannot say if two taxa, M. x p. & M. x p. v. are same or not.
My 2nd Q. is if a hybrid can have characters of one or both of its parents. I think yes.
I will check probability of this species to be Mentha x piperita L. –
Now, you place your points in favour of M. spicata …!
One more point in favour of M. x p. = calyx 3-4mm (against 2mm in spicata).
